Open arbitary file from Finder in TextMate In Finder, I see a file with the ".rel" extension.  I'd like top open it in TextMate.  I don't see TextMate in the list of choices, and, in fact, can't find it anywhere in the list of applications when I try to choose the application to open it with.

How can I tell Finder to open the file in TextMate, either now or always (by default)? How can I open an arbitrary file (i.e. even one with a known extension) from Finder in TextMate?

TextMate v2.0-beta.6
OS X Yosemite 10.10.1
Select the file in Finder.
Press ⌘I to Get Info.
Set None to Other… in the Open With section of the inspector:


Enable All Applications, then find and choose TextMate.
Select Change All… to change the association for all .rel files.
