I am wondering if TextMate has any kind of emacs-like 'set mark' feature. I found an old list msg that indicated it did not in 2004: http://one.textdrive.com/pipermail/textmate/2004-October/000938.html but it looks like it was in the pipe, though I haven't run down any newer info. (I can see that my cocoa keybinding of 'ctl-space' to 'set mark' does not work even though most of my key bindings are preserved in textmate).
