I want to master TextMate

Sadly, my powerbook is currently kaput (I dropped it). I'm trying to decide whether to pay to fix it or just get a new MacBook. While RadRails is a nice stand-in on Windows and Ubuntu, I am going through TextMate withdrawal.

In the meantime, I can live varicariously through others.

Mike Clark has posted a nifty cheat sheet for Rails coding in TextMate.

There are several others out there:

• For SyncPeoplebundle [pdf]
• g-design [pdf]
• Migrations

It might be nice to collect all these into a concisely formatted little popup/tool-tip you could invoke while using TextMate.
