TextMate's hidden "Find in Selection"

[16:30] srogers:
So what's up with TextMate and replace string in selection?
i.e. why is it not there in the find dialog?

[16:37] marsipan:
srogers: hold down the option key while in the Find dialog
"Replace All" becomes "in Selection"

[16:38] srogers:
cool
thanks
(seems like checkbox would be better though)

[16:39] marsipan:
agreed.
