TextMate is my default editor since it has lots of perks where other editors don't fill my needs.
Last week I was looking for a simple way to insert code snippets into some slides in Keynote which didn't seem that easy to do at all. In the end I just took some screenshots until today, when Mathias showed me this TextMate bundle on GitHub.
So far this is the coolest bundle I found, hope you enjoy it as much as I do.
