I can appreciate that's his personal preference, but there's  
something to be said for being consistent with the OS (particularly  
when they claim to "bring Apple's approach to operating systems into  
the world of text editors"). I've never even encountered this type of  
keystroke-level undo until TextMate, and I find it slows me down  
considerably. Please make chunks a preference!

Re: slowdown, I read about something involving the caching, and I did  
flip a defaults write, so app switching does seem a bit better..but  
tab-to-tab is really sluggish, and I'm on a dual 2 G5. This is just a  
text editor, I can't imaging what's happing behind the scenes that  
causes this.
