[TxMt] Dvorak/Querty Keyboard Layout

I use the presumably obscure Dvorak/Command-Querty keyboard layout. It uses Dvorak for standard typing, but when you hold down the command key, it switches to Querty, so I can use the key that's actually printed on the page, and preserve that precious command key muscle memory. I've had mixed success using the command keys with TextMate, though. For instance, I frequently change the indentation of blocks of code, using command-[ and ]. When I use DQ, I tend to get some sort of commenting. If I switch back to regular querty, I get the results I expect. Is there any way this can be improved?
