I pressed control alt shift B and then clicked on one of the popup items:
Blog – HTML
Blog – Markdown
Blog – Text
Blog – Textile
LaTeX Beamer

Now all of my syntax highlighting is gone.

I was edting javascript. How do I get textmate back to normal?
And more generally, how do I figure out what that keyboard shortcut did without asking the mailing list? (I searched for a long time to no avail).

Thanks.
