Like many, I’m one of the loyal user of the TextMate application. I was fine withTextMate for all the days, until few weeks. The  Command + Arrow keys ( ⌘↑/⌘↓/⇧⌘↑/⇧⌘↓ ) didn’t work properly. I was not sure what was the sudden break in the application. Problem seems to be strange and thought that it’s only with my system. Then went tweaking some thing in TextMate , reinstalling TextMate : nothing worked. So, at-last planned to give up TextMate but wanted to do a last try.  When I did a google again, came across the same defect logged in the macromates ( developers of textmate ) site and realized that my recent snow leopard upgrade have made the TextMate numb. And fortunately, they had a fix too. Good it worked.
