self-insert-command can do it -- so can you, then :-)

To find out (it helps to have the Emacs sources around, you do `C-h f'
self-insert-command, and Emacs tells you:

  "self-insert-command is an interactive built-in function in `C source
   code'.

   It is bound to many ordinary text characters.
   [...]"

The `C source code' above is a link, and if you have the Emacs sources
around, it'll take you to the relevant C function. There you see that
it references some variable `last_command_event'.

Lo and behold, Elisp has a corresponding variable `last-command-event'
where you can look up what triggered you `my-self-insert-command'

Hope this gives you a pointer to play with.

Regards
