shortcuts, audio & magic zoom

[mojo]

I tried and have 2 qns, currently using 600D & ML 2.3...

1) Shortcut menu doesn't support audio in/out adjustments

2) How can i configure L:int/R:ext (or L:ext/R:int) ?

3) Although it is mentioned in the menu's help, press [Info], half shutter press to trigger Magic Zoom when recording is not supported.

Am I correct?

Regards
