Try this: Press Control-Command-T, in the little magnifying glass drop down choose "Key Equivalent" and then type Cmd-Opt-O, and see if any results show up.  This will be language-scope-aware, so do this in the files you normally work in.

Dru, thank you, your suggestion led me to find the interfering culprit.

I have something called 'sidenote', whose shortcut for unfurling from 
the left screen edge was just the shortcut that Textmate uses for the 
insert/overwrite toggle.  Once I changed that one to a different 
shortcut, Textmate's toggle began to work.

This prompts two questions:

1 - how does one alter Textmate's shortcut keys?
and
2 - is there an OSX utility to list all of a system's shortcuts to help 
the user avoid conflicts?

#2 may be asking too much, tho.
