using Command with my thumb in OSX is way less ergonomic than ctrl with pinkie on Windows. I don't know if I'll ever get used to that.
Change Option to Alt.
Shift mousewheel should be horizontal scroll.
Yeah but jumping to shift is a workflow killer for me, slows down the process big time :/
Literally man my pinky is on Option and ring finger on Command ALWAYS when I am in Reaper, and I can do everything from there. While drum editing I don't let go of option at all and I just add command to it whenever I need to. It's a
lot faster than taking my finger off of option, going and holding shift, and then coming back to option.
It sounds trivial but the extra time adds up, I fly in that program like you wouldn't believe.
The other crappy thing is on OSX I use Ctrl+(some key) for all my "do this action but at the mouse cursor instead of the edit cursor" functions. Can't use the Win key for that in Windows unfortunately because the OS steals most of those commands
I don't think I could comfortably work with a Windows keyboard in Reaper under Windows because of the placement of the Windows key either. You don't have any fully functional modifiers
side by side on a Windows keyboard (since it goes Ctrl-Win-Alt and Win only works for some things). The side by side thing is crucial for speed and comfort. Trying to hold Alt and then adding Ctrl and then pressing B is a lot more awkward and uncomfortable than holding Option, adding Command and pressing B.
In general on Windows, the only two modifiers that I find reasonably efficient to hold and combine are ctrl+shift. But then the only letters on the keyboard that are efficient to reach are D, S, C and X because your hand is cramped up in the corner. Also, when you let go of shift and have your ring finger free, it becomes useless because it can't comfortably reach any key besides
maybe[i/] A, Q and Caps Lock (but your middle finger is still the most efficient choice for A if you want to get back to shift quickly.
I could probable make it work, I would just have to remap EVERYTHING so that it was all based on ctrl+shift (which actually is a little more ergonomic/comfortable than option+command) and only use this section of the keyboard...
By contrast though, I get an entire extra row of letters within easy reach under OSX because my hand is shifted one row over. I'm not wasting reach on stupid keys like Caps Lock...
I do prefer "ctrl+c, ctrl+v" etc. for copy and paste and stuff though. It's too bad there's not an easy way to adopt that over on a Mac for the whole OS. The thumb thing does suck. But for something like Reaper where you can map all your own key commands to maximize efficiency, the OSX keyboard is a huge win.
