jot, jotxgizmo - mouse-based text editor
jot [-fvMx] [-p n,n,n,n] [-l n | +n] file ...
Jot is a display-oriented cut-and-paste style ASCII text editor tuned to
run on Silicon Graphics machines. Jot is written using pure Graphics
Library code, and hence will not work on a generic X terminal, and it
ignores the X resources. Jot (which was originally called "zip"), is
tuned to run well on large files, and can edit arbitrary binary files.
Invocation Options [Toc] [Back]
-f Run jot in the foreground. This is often required if you wish
to use jot as your mail or news editor.
-v In view-only mode, jot will not allow you to modify the file
you are viewing.
-M Mmap the file. This can nearly double the start-up speed for
large files, but may not work reliably on remote-mounted files.
-x Backup override -- overrides saving of backup and checkpoint
files.
-l n
+n Start jot at line n of the file. If this option is specified as
+n, this flag must come after all the other options and before
the first file name.
-p n,n,n,n
Place the jot window at xmin,xmax,ymin,ymax. To specify the
size and not the position, use negative values for xmin and
ymin to indicate the dimensions -- in this case, the xmax and
ymax values are ignored. For example, -p -400,0,-600,0 makes a
window 400 pixels wide and 600 high.
The file argument indicates a list of files to be edited. If more than
one file is named, jot edits the first, and adds the others to the reopen
list. If no file is specified, and the jotcruft option is set in the
.jotrc file, jot will come up with the same file and reopen list it had
when you last quit jot in that directory. See the section on USER
PREFERENCES, below.
The ASCII file .jotrc in your home directory contains user preferences.
The parser is pretty idiotic, so errors in this file can cause problems.
Each option must appear on its own line. A '#' character at the
beginning of a line will comment it out.

User Preference Options
autoaddnewline This will cause jot to add a newline to the end of
each file if one is not present. Even without this
option, you will be warned about a missing final
newline when you write a file.
autoindent When you type <Enter> or jot automatically breaks a
line in word-wrap mode, jot will add enough white
space at the beginning of the line to match the
indentation of the previous line.
autosavecount # Every # keystrokes, jot will automatically make a
checkpoint file with a ".sav" extension.
backups When you start jot, or visit a new file, a backup
version of your file is written with a ".bak"
extension.
colors # # # # Sets the GL color index values of the background,
text, cursor, and selection. Jot does not change the
color map; it just uses the mapped colors it finds.
See markcolor.
commentcolumn # This sets the column number used by the insertcomment
command.
cyclesearch This starts jot in cycle search mode in which search
commands automatically continue through all the files
in the reopen list.
dblclktime # Sets the time in 1/100 seconds for the double click
time for jot. The default is 20.
electriccmode When a file with extension ".c", ".h", ".C", ".l",
".y", ".v", ".dv", ".iv", ".C++", or ".c++" is
visited, jot is put into electric-c mode, and some
commands behave slightly differently.
expertmenus More extensive pull-down menus appear.
fontpath path path is an absolute path name for a font to be used
instead of the default for text. The font must be in
.pcf format (or .pcf.Z format), and must be fixedpitch.
hardtabsize # sets the tab size for physical tab characters. (See
the description of tabs under GENERAL FEATURES.)
incrsearch Puts jot in incremental search mode. When a new
search is begun with <A-F>, as each character is
typed, the search continues to the next place in the
file that the string so far typed appears. For
Page 2
JOT(1G) JOT(1G)
example, if the cursor were at the beginning of this
paragraph, and you searched for "thex", the "t" would
put you at the "t" in "Put" in line 1, the "h" in
"with" in line 2, "e" to "the" in line 3, and "x" to
the "thex" in line 6. Type <Esc> or any other noncharacter
command to get out of the search mode.
jotcruft Causes jot to save a file with the name ".jotcruft"
in each directory where you exit from jot. The
.jotcruft file contains the currently open file and
the files in the reopen list, together with the
selections and marks defined in those files. If you
invoke jot without a file name, the state in the
.jotcruft file will be restored. If jot is invoked
with a file name, the .jotcruft information is
ignored.
leftscroll Puts the scroll bar on the left. Motif requires a
right-hand scroll bar, which doesn't make much sense
for text editors.
linenumbers Causes jot to display line numbers by default.
locale file Jot reads the file named file to get
internationalization information. The file must
contain the correct messages in the correct order.
mapkey key meta cmd Remap a command to a different key. The first entry
is the key name, as specified in the file
/usr/include/gl.h, like AKEY, ZEROKEY, et cetera.
The meta entry is one of NONE, SHIFT, CTRLSHIFT, ALT,
ALTSHIFT, ALTCTRL, ALTCTRLSHIFT, and the third is the
command name. A complete list of command names
appears under COMMAND NAMES, below. For example:
mapkey CKEY CTRLSHIFT ENDFILECMD
will cause jot to move the cursor to the end of the file when you hold
down the control and shift keys and type the 'C' key.
margin # Sets the right margin which is used in word wrap mode
and for paragraph reformatting. It is in column 72
by default.
markcolor # The color index for the marks and line numbers. See
colors.
nobrowsegizmo Causes jot to use its internal high-speed file name
chooser instead of the browse gizmo. If the
browsegizmo is not installed, jot will always use its
own file chooser.
Page 3
JOT(1G) JOT(1G)
nocase Causes searches to be case-independent by default.
oldstyle Runs jot in the old default zip modes -- the old fast
font is used, the scroll bar is on the left, the
right mouse button pans, and expert menus are
enabled.
oldaccelerators Runs jot with the original Alt key accelerators.
Accelerators are also called "speed-keys" or
"shortcuts" position # # # # The numbers represent
the same values as in the "-p" command line option to
jot.
rightmousepan Pressing the right mouse button pans the text, rather
than invoking a popup menu.
tabsize # Sets the tab column size. See "tabs" in the GENERAL
FEATURES section.
undobuffersize # Sets the size of the undo buffer. By default it is
2000. Commands of differing complexity use different
numbers of undo buffer entries. Most commands use
only a few entries, but a global search/replace can
use a large number of entries. There is no penalty
(except for process size) for having a larger undo
buffer. The undo buffer is a circular queue, so
normally a few hundred operations can be undone.
wordwrap Enables word wrapping when you type with your cursor
at the end of a line past the right margin. Adding
text in the middle of the line will not word-wrap.
Use the reformat command (<A-R>) to reformat such
paragraphs.
If your window manager has window headers, jot displays some interesting
information in its header:
* (asterisk) indicates that the file is modified.
[Macro F* Open] Macro F1, F2, ..., or F12 is being created.
[Incr search ...] Jot is doing an incremental search.
[View Only] The file is open in view-only mode.
COMMAND SUMMARY
In the descriptions, 'A' stands for the left Alt key, 'C' for a Control
key, 'S' for a shift key (where emphasis is needed), and the '<' and '>'
symbols bound the command. Note that although there is a right Alt key,
it is reserved as a "compose" key for internationalization. For example,
the command "<C-a>" means to hold down the control key while you type a
Page 4
JOT(1G) JOT(1G)
lower-case 'a'; "<C-A-P>" means to hold down both the control and alt
keys while you type an upper-case 'P'. There are two sets of keyboard
commands. The first table lists the default command accelerators. The
second set of accelerators is used when "oldaccelerators" or "oldstyle"
at set in the $HOME/.jotrc file. These are the default accelerators from
previous versions of jot.
Commands followed by an asterisk are explained further in the GENERAL
FEATURES section.

GENERAL FEATURES
Tabs
By default, literal tab characters in a file advance to the next column
that is a multiple of 8. If jot's tab size is something other than 8,
then pressing the tab key advances to a column that is a multiple of that
tab size, but it does so by inserting the appropriate combination of tab
characters and spaces. In addition, it will clean up spaces before the
cursor when the tab key is pressed.
For example, if the tab size is 5, and the cursor is at the beginning of
a line, the first tab key press will insert 5 spaces. The second press
will delete those 5, add a raw tab, and then 2 more spaces to advance to
column 10. The next tab inserts 5 more spaces, and so on. The tab size
can be anything; if it is 17, for example, the first tab from the left
margin will add two tab characters and 1 space character.
Page 10
JOT(1G) JOT(1G)
If you set the hard tab size this will make physical tabs advance by a
different number of columns. Usually it is not a good idea to do this
since so many UNIX utilities depend on a tab size of 8.
The <Backspace> key deletes the character before the cursor, so if the
tab size is 4 and you type tab twice from the left margin, there will be
a single tab behind the cursor. A backspace at that point eliminates the
tab character and will put the cursor at the beginning of the line. The
<Delete> key is exactly like the backspace key unless there is a tab
character before it. If so, the tab is first converted to the
appropriate number of spaces, and then the final space character is
deleted. <Delete> thus moves backward one column at a time, no matter
whether it is passing tabs or any other character.
The Command Multiplier [Toc] [Back]
If the <Alt> key is held down while a decimal number is typed, that
number becomes the command multiplier. It can have multiple digits. For
example, to get a command multiplier of 25, type <A-2><A-5>.
Normally, the command multiplier is the number of times the next command
is to be repeated. <A-1><A-7>a will insert 17 'a's into the file. <A9><A-n>
will move the cursor down by 9 lines.
A few commands interpret the command multiplier differently. The indent
and outdent commands interpret the multiplier as the number of columns to
indent or outdent (the default is 4). The reformat command interprets it
as a margin for reformatting. The jump to line and jump to column
commands interpret it as the line or column to jump to. For example,
<A1><A-2><A-7><A-j> jumps to line 127.
A command multiplier in the jump to mark, delete mark and set mark
commands is interpreted as the mark number.
The command multiplier is also used to insert non-standard characters
into the file. See "Typing Weird Characters", below.
Typing Weird Characters
There are 2 ways to insert control characters and characters outside the
ASCII character set into the file. If a command multiplier is followed
by an <Esc>, the number is interpreted as the ASCII code and that number
is inserted. For example, to insert a 'control-A' (ASCII 1) into your
file, type: <A-1><Esc>. Unfortunately, you have to specify the character
in decimal.
The other way is to use the <C-Esc> literal escape mechanism. To insert
an ASCII 'control-a', type: <C-Esc><C-a>. If you want the high order bit
of your character turned on, hold the <Alt> key down while you type the
next character. So if you want ASCII 129 (which is the same as
'control-a' with the high order bit on), type: <C-v><C-A-a>.
Page 11
JOT(1G) JOT(1G)
This method can be used to insert unusual characters in search and/or
replace strings. Jot cannot, however, search for or replace the newline
character.
Non-standard characters are displayed in jot as 3-character sequences.
The first character looks like an 'x' with a box around it, (unless
you've chosen a non-default font, in which case it's an 'X'), followed by
2 hexadecimal characters. An ASCII 'control-a' looks something like
this: "X01".
Electric-c Mode [Toc] [Back]
In this mode, certain parenthesis-matching operations are performed, tabs
are set to 4, and auto-indent is enabled. Some automatic spacing and
indentation is also performed. It is quite conservative, and it is not
customizable.
The Reopen List [Toc] [Back]
In a jot session, each time a file is visited, it is added to the reopen
list. When a new file is opened, the previous file's position in the
window, selection, and marks are all saved in the reopen list so that
revisiting a file puts you back in the same place. A roll-over menu
(with long menus enabled) allows easy access to the previously visited
files.
If you simply click on the reopen menu entry without rolling over, you'll
visit the previous file, making it very easy to flip-flop between 2
files.
File Name Typein
When using the simple jot file browser, often it has a guess at the file
name which is presented. Typing <Enter> selects that name, but typing
any character erases the entire guess and allows typein from scratch. To
modify a guessed name, click the cursor in the typein field, and then
begin typing. The paste command works in the typein field as well.
While typing, <Esc> attempts file name completion. Typing <uparrow> and
<downarrow> go though possibilities. Typing <rightarrow> goes down a
directory, and <leftarrow>, up a directory.
Macros [Toc] [Back]
Any sequence of keystrokes, including command multipliers, can be saved
in macro definitions. Up to 12 macros invoked by the keys F1, F2, ...,
F12 can be saved, and the macros can be nested.
To define a macro, say F3, type <C-F3>, then type the commands you want
(jot will perform the commands as you do them), and end the macro
definition with another <C-F3>. For example, to make a macro that adds a
semicolon to the beginning and end of a line and then advances to the
next line, type: "<C-F5><C-a>;<C-e>;<C-n><C-F5>". Then to perform this
operation on the next 150 lines of the file, type: "<A-1><A-5><A-0>F5",
using the command multiplier.
Page 12
JOT(1G) JOT(1G)
All the current macros can be saved in the file ~/.jotmacs using the save
macros command.
Scroll Bar [Toc] [Back]
In addition to the usual things a scroll bar does, the highlighted
portion of jot's scroll bar indicates roughly the size and position of
the current selection within the file. In addition, if any marks are
set, the corresponding numbers are shown in the scroll bar. The size of
the thumb is proportional to the size of the viewed window in comparison
to the size of the whole file, unless the file is huge, in which case the
thumb is some minimal size. There's a hole in the thumb to see the
selection and marks through it.
Search Commands [Toc] [Back]
The repeat search repeats the previous search command, unless there is a
non-empty selection that is less than a whole line, in which case the
search is for that. Thus to find the next occurrence of a word that
already appears as text, double-click the word, and type <A-f>.
Regular expression search and replace commands use the regular
expressions recognized by "ed". Try "man ed" for more information. Jot
cannot search for regular expressions containing a newline.
Ctags [Toc] [Back]
Jot has a "Jump to tag" command that searches for a file called "tags" in
the current directory produced by the program ctags. If a word is
selected (usually a procedure name), jump to tag will use that word as
the tag name; otherwise, it will ask for the name.
Transpose [Toc] [Back]
If the selection is empty (the cursor is between two characters, the
transpose command swaps the characters on both sides and advances to the
right. This makes it easy to drag a character to the right an arbitrary
distance.
If there's a non-empty selection, the entire selection is reversed. There
is no good reason to do this, but the results can be really entertaining.
Split Window [Toc] [Back]
Jot only knows about a single window, but the split window command fires
up another version viewing the same file. The two jots are completely
independent, but one is made view-only for protection.
Cut and Paste [Toc] [Back]
Jot originally ran on non-X platforms, and used a cut and paste strategy
where the buffer was saved as /tmp/.cutbuffer. This mechanism remains,
together with the X-based cut and paste commands. Jot effectively has
two cut buffers.
The non-X cut and paste buffer can be appended to, so it is easy to
collect a lot of text from a file using <A-z> and paste it all at once.
Page 13
JOT(1G) JOT(1G)
To cut and paste text to and from other X processes requires the X cut
and paste mechanism. Each text selection automatically becomes the X
selection, and <middlemouse> pastes it. It doesn't behave exactly as
most X processes, however, in that making a selection in another process
does not unselect the jot selection.
Undo and Redo
Each time the undo command is invoked, jot undoes one more operation.
For example, if "abcde" is typed followed by 3 undos, first the 'e', then
the 'd', and finally the 'c' is removed. Redo steps forward, undoing the
undos. After some undos have been typed, a single non-redo command
clobbers any possibility of continuing with the redo sequence.
Filters [Toc] [Back]
An arbitrary UNIX command can be applied to the current selection, and
the results of the filter are placed in the (non-X) cut buffer. For
example, to sort a bunch of lines, select them (including the final
newline), invoke the filter command with <C-G>, and type "sort" as the
filter command. The sort command executes, and the output replaces the
contents of the cut buffer, the first few lines of which are displayed.
Thus, a simple paste replaces the original selected lines. If you make a
mistake, just don't do the paste, and try again. And there's always
undo.
The filter command can take the UNIX command from the cutbuffer so it can
be used in macros. It can also redirect the output to the invoking shell
so that compiles, for example, can run independently of the rest of the
jot session.
Marks [Toc] [Back]
A mark is simply a position between a pair of characters in a file. The
marks stay between the same two characters, if possible, so if the mark
is near the end of the file, and characters are typed near the beginning,
the mark effectively moves further from the beginning. There are 10
marks available, numbered 0 through 9. The positions of the marks are
roughly displayed in the scroll bar by their corresponding numbers.
Clicking with the right mouse button on the mark in the scroll bar places
the cursor at the mark.
The selection is bounded by two text pointers. If the selection is
empty, the two text pointers are at the same place. There are commands
that take the text pointers and convert them to marks and vice-versa, and
a command to swap the marks and the text pointers. This is often very
useful in macros.
Kill to End of Line
If there is any text beyond the cursor in a line, <C-k> kills to the end
of the line, but does not kill the newline character. If there is no
text, <C-k> kills the newline, appending the current line with the next.
Thus usually two <C-k>s are required to kill each line.

However, if there is a command multiplier, it is used as the actual
number of lines (including newlines) to kill. <A-3><C-k> kills 3 entire
lines.
Finally, repeated <C-k> commands append the cut material to the contents
of the cut buffer -- the first <C-k> replaces the cut buffer with the
kill contents and each successive <C-k> adds more to the cutbuffer. <Cu>
(kill to beginning of line) does not append successive kills to the
beginning of the cutbuffer as might be expected.

Jot was originally called zip, and was written by Tom Davis and Derrick
Burns of Silicon Graphics. Some of the conversion from zip to jot was
done by Chris Eveland of Silicon Graphics.

Line numbers only work correctly for files with fewer than 100000 lines.
When you run "jot -M" over a network on a remote file, sometimes jot just
dies and goes away with no warning.
