[TxMt] 'undoing' for days [gripe]

[kumar mcmillan]

Sorry to gripe, but pressing undo after writing a line of code is like 
trying to walk up a downward moving escalator.  I know it's been said 
before but here is another plea to the steadfast, cooperative 
developers: at least consider an option to let undo step back word by 
word instead of character by character (what would be the nicest is to 
step back in logical "chunks" the same way bbedit does).

thanks, Kumar
