If you’ve just upgraded to Revision 1616 of Textmate, you may be wondering why your next and previous file tab keys stopped working. The author of Textmate recently changed the next and previous file tab key shortcuts to the universal mac application equivalents. Here it is in the release notes:
[CHANGED] Change next/previous file tab key equivalents to shift command [ and ]. This has become the de facto standard.
I tried to deal with this for a few days but that keyboard shortcut is just too ingrained in my brain. You can fix this, though, by going in to your Keyboard preference pane, then the "Keyboard Shortcuts" tab. Under "Application Shortcuts" click the plus button, find TextMate, and add the following:

Voila. Fixed! Now you can get back to coding at the speed of thought.
Thanks, that was driving me crazy!
Yes! Strong work.
Thank god, this freaked me out completely
Cool! See this tiny apple script I wrote to automate the shortcut binding:

Thank you! Show stopper for me.
Do not forget to change your keyboard batteries soon ;)
Thanks so much, I ended up changing mine to mirror Safari Cmd+Shift+Arrow. Since when is the bracket key the de facto standard for replacing the more obvious arrow keys?
I’m not sure but I know it’s been like that for a very long time. For most applications I think it works well enough — your hands dont have to move very far from the home row. For TextMate, however, it’s so ingrained in me to use those keys I can’t switch.
I’m maybe one of the few who had the opposite reaction; I remapped my TextMate tab-switching to cmd-shift-[ & cmd-shift-] over a year ago simply because those were the shortcuts for everything else in OS X, and I wanted them to be the same.
Nice. Sane defaults are sane. No longer will I suffer with the arrow shortcuts when using somebody else’s machine (i.e. when pairing).
Phil Crissman: You are definitely not alone. I also value consistent keyboard shortcuts.
Thank you very much. Searching Google and reading your post was faster than accessing my poor memory to remember how to change a keyboard shortcut in System Preferences :)
Thanks for the tip. That was driving me nuts and I wasn’t getting used to the new shortcuts.
thanks jason man. i thought i was going crazy!
Thanks – I was totally wrong footed by this too.
