[emacs-wiki-discuss] emacs-wiki and abbrev mode

[Charlie Martin]

... or really, mostly, abbrev mode.

I keep wanting to have abbrevs that expand out to, say, date-time stamps.  I 
can do this on my mac with the rather brilliant Texpander, where for example I 
have it set up so that typing 'ttime' inserts  12:13:25 ... and then 12:13:35 
... and then 12:13:42 ... and so on.


So here's my question: is there a way to get abbrev mode, or hooks in 
emacs-wiki or muse-mode or some such, to act like an abbrev but execute a 
fragment of lisp code instead of just replacing one string with another?
