Inside Macintosh Vol. 1, page 379 deals with that.  I quote:

Assembly Language note:  The highHook and caretHook fields -- at the offsets
teHiHook and teCarHook in assembly language -- contain the addresses of
routines that deal with highlighting and the caret.  These routines pass
parameters in registers; the application must save and restore the registers.

I'll stop here because my fingers are tired :-).

Be aware that I've never used this, but since I knew it existed, I thought
I'd point it out.
