[TxMt] Mercurial Bundle shows status only for the current open file

[Thomas]

You are right it works. But that's not very convenient, is there a way
I could customize a shortcut to handle that?

Also I see that to invoke Mercurial, I have to use ctrl+shift+M, but
if I am currently in another bundle, it triggers another keyboard
shortcut. How can I customize TM for that? Is there a way to quickly
swith between bundles?

I am a TextMate newbie.
