I am a new user of Texmacs. I want to use Texmacs primarily for notetaking, doing mathematics and physics excercises, literature research etc. My hope is to replace, more or less, pen and paper for these tasks.

In order to make some progress in that direction, I am trying to understand how keybinding are done in Texmacs.  While I understand the mechanics of making keybindings and using an init file, I am still struggling. I have some questions.

1. How do I find out which keys are currently bound in the mode where the cursor is?

2. Given a keybinding, how do I find out its definition?

3. Give a Guile-function, how do I find the associated documentation(, if there is any)?

3. How do I find out about existing guile functions which may be of use when defining my own set of keybindings for editing? I have found glue-editor.scm. Is this the only relevant file?

4. In general, what resources should I look into for finding out what the Guile-interface has to offer, as far as editing goes? Text and math editing is my priority at the moment.
