Hi,

there is no such master table (well there is, see more later). You
have some routines inside progs/kernel/gui/kbd-define.scm which might
help you. Specifically kbd-find-key-binding. Open a scheme session and
try this:

(kbd-find-key-binding "F1")

this returns a one element list with the command associated with the
key F1 in your current "input mode" (which is session mode):

(#<procedure #f ()> "")

So you'll want to take the first element of it and display the source code:

(procedure-source (car (kbd-find-key-binding "F1")))

This should output the following:

(lambda () (interactive docgrep-in-doc))

Now, keys can be overloaded, meaning that different contexts have
different commands assigned to keys. This is achieved with kbd-map
like this:

(kbd-map
(:mode in-math?)
("F1" (some-command-to-show-math-help)))

But kbd-find-key-binding shows only what is defined in the current
context. You'd need to use kbd-find-key-binding2, but this function is
not exported outside the file kbd-define.scm, so you'd need to
redefine it using (tm-define blahblah...) instead of (define
blahblah...)


As to the master table: you could use the hash table kbd-map-table,
but again it's not exported outside kbd-define.scm. And again you can
trick and modify that file inside the application bundle, then
relaunch TeXmacs to have access to all the data, then traverse it and
nicely format it.

This would actually be a nice thing to have...
