Anyone know how I can tie a series of keystrokes to a vs macro?

I have a custom macro I want to run when TT is typed in command mode.   

If not, is there a way of doing something like:

:abc

to run the macro instead?

So far I have to tie my macro to Ctrl-T, Ctrl-T in the VS keyboard mappings.  I prefer not to have to use ctrl/alt combos to run the macro.

Thanks.
