[TxMt] Keyboard shortcut to set file type

[Guoliang Cao]

Hi,

I've been using TextMate for almost a year now and like it very much. 
I'm trying to stay off my mouse and here is one task I think I should be 
able to do without using mouse. From time to time, I copy some code to a 
new editor window and run. What is the keyboard shortcut to invoke the 
file type dropdown in the bottom of the editor?

Thank you.
