kbdset - attach to kbd mapping tables, set modes
kbdset [-oq] [-a table] [-v string] [-k hotkey] [-m x] [-t ticks]
kbdset [-oq] [-d table] [-v string] [-k hotkey] [-m x] [-t ticks]
The kbdset command is the normal user interface to the kbd STREAMS
module. [See kbdcomp(1M) and kbd(7) for a general description of the
module's capabilities.] kbdset allows users to attach to pre-loaded
tables, detach from tables, and set options. Options are provided for
setting hot-keys to toggle tables and for controlling modes of the
module.
Arguments and options are scanned and acted on in command line order. If
the -o option is given, subsequent options affect the output side of the
stream, otherwise the input side is assumed.
The -q option causes the kbdset command to list modules which can be
accessed by the invoking user. In this case all subsequent options are
ignored. The output from the -q option lists the user's current hot-key
settings, current timer value, and for each available table an
identifier, the name, size, attachments (input and/or output sides),
reference count, number of components, and type (private or public). In
the following example, there is one composite table, two tables are
attached on the input side, and one on the output side.

The ID field is an identifier unique to a given table (actually its
address in memory). Currently attached tables are marked i or o;
otherwise, the I/O fields are marked with a dash. Ref is a reference
count of attached users (including composites that refer to simple
tables) and if non-zero, indicates that the table is in use. Size is the
total size in bytes of the table and associated overhead in memory. If
the table is a composite table, the Cmp field contains a number instead
of a dash, and the following line lists an identifier for each component,
in order of processing (allowing identification of the components in a
composite table). Publicly available tables are marked with the type pub
and private tables with pri. Private tables are available only to the
invoking user and within the current stream. Tables which are really
external functions [see kbd(7)] are marked ext; they are always of type
pub. Tables that are interpreted in timeout [see kbdcomp(1M)] mode have

an asterisk (*) preceding the Type field; members of composite tables
that are interpreted in timeout mode have an asterisk after their
bracketed identifier (on the second output line). External functions are
never time-sensitive, unless by their own internal specifications.
The option -a accompanied by an argument attaches to the named table. A
table may not be multiply attached by a single user. When a table is
attached and no other table is already attached, then the table is
automatically made current. The option -d detaches from the named table.
[See kbdload(1M) for a description of how tables are loaded.]
The -k option sets the user's hot-key. Setting a hot-key with only a
single active table allows mapping to be toggled on and off, depending on
the hot-key mode. A hot-key is a single byte, typically set to a
relatively unused control character, that is caught by the kbd module and
used for module control rather than being translated in any way. The key
used as a hot-key becomes unavailable for other uses (unless it is
generated by mapping). The hot-key may be reset at any time,
independently from other options. Note that kbdset does not interpret
^X-type sequences; it expects a literal hot-key character.
The -m option with an integer argument controls the hot-key mode. Legal
modes are 0, 1 (the default), and 2. Mode 0 allows one to toggle through
the list of attached tables. Upon reaching the end of the list, the
cycle returns to the beginning of the list. Use of Mode 0 with only one
table loaded does not allow mapping to be turned off. Mode 1 toggles to
the unmapped state upon reaching the end of the list (for example, given
two tables, the sequence is table1, table2, off, table1, and so on).
Mode 2 toggles to the unmapped (or off) state between every table in the
list of attached tables (for example, given two tables, the sequence is
table1, off, table2, off, table1, and so on).
The -v option turns on verbose mode, which can be useful when multiple
tables are used in interactive sessions. In verbose mode, the name of
the table can be output to the terminal whenever the user changes to a
new table with the hot-key. The string associated with the option can be
any short string. If the character sequence %n appears in the string,
the name of the current table (or a null string) will be substituted for
the %n. (A null argument to -v is equivalent to terse mode.) One useful
sequence for this mode is save-cursor goto-status-line clear-to-end-of-
line <b>%n restore-cursor. This causes output of the current table name on
the terminal's status line; in absence of a status-line, a simple
sequence is to print the table name and RETURN [see terminfo(4) for the
appropriate escape sequences.] Verbose mode is only available to show
input table status to the output side of the stream. The output string
for verbose mode is not itself passed through the mapping process, but is
transmitted directly downstream with no other interpretation (it should
thus be a string of ASCII characters or in some other externally
available code set).

The -t option with an argument is used to change the timer for tables in
the stream that are interpreted in timeout mode. Values (in clock ticks)
between 5 and 400 are acceptable. (Depending on the hardware, the clock
is usually either 60Hz or 100Hz, thus one tick is either 1/60 or 1/100 of
a second; with a bit of experimentation, a suitable value for one's own
system and typing speed can be found.) When a table that uses timeout
mode is attached, it is assigned the current timer value. All tables
that are attached after setting the timer value will take on the new
value, but tables currently attached are unaffected (this allows one to
set different values for different tables). The option does not affect
other users' values. The timer value may be set independently for input
and output
sides by using -t in conjunction with -o. The value for a currently
attached table may be reset by detaching the table, setting the value,
then re-attaching the table.

values for input and output sides of the module.

A table may be detached while it is current; however, in this case, it is
first made non-current; this allows error recovery under adverse
circumstances. Detachment of a current table is not affected by the
current hot-key mode, but always toggles to a state where no table is
current.
It is not possible with the -q option to see the timer values assigned to
currently attached tables, nor to reset the value for a table that is
currently attached.
