I also think the Blind button can then become a toggle.
The respective "Mode" buttons takes you to the mode in Live regardless of the Blind/Live state. Blind is always a toggle which does not change "Mode".
Changing to Looks really needs to not change high-lighted page in the Looks Directory(sticky from the previous use). And all of the keystrokes we are used to using for editting and recording that we currently have in Cues need to work in Looks.
An indicator in the Looks directory for the Look Page active on the submasters would be huge. Simply changing the "highlighted" page for viewing/editting live or blind should not change the hardware.
I REALLY like John's shortcuts - CTRL-C(Cues), CTRL-L(Looks), CTRL-P(Patch), CTRL-V(variables), CTRL-E(Events), CTRL-B(Blind/Live Toggle), CTRL-T(Levels/Times Toggle), CTRL-F(FX

Gooze's Idea of cycling through the pages as you press Next/Last and the "Mode" key is useful but a bit of a finger twister for CTRL-L+TAB and CTRL-L+SHIFT-TAB. But I guess the OLE user needs to suffer in some ways.
