With the huge plethora of actions available in Reaper, the keyboard is not enough as it is, and it will be worse as actions are being added :) What about having the abiity to use shortcuts made of two keypresses? For example, using "t" as a shift for track oriented functions, so that pressing "c" while "t" is pressed can be configured to trigger the "set track to custom colors" or "r" while "t" is pressed can do "set track to random color" and so on. It's like having the ability to configure new shifts for grouped functions ("i" for items, "t" for tracks, , "m" for markers, "r" for region, "l" for loop and so on). No factory defaults, but the ability to use this feature. Worth going in the issue tracker for FRs? I'd personally use it a lot, because I could organize shortcuts in a much more logical and mnemonic way. And, it seems to me innovative enough to be added to Reaper organically, allowing a tremendous workflow acceleration. - Mario
