That really does sound like a better combination! Never done system remappings on OSX, how did you go about it?
Hi. On OSX it's actually very easy (at this point in history):
1. download & install Karabiner Elements (open source: https://github.com/tekezo/Karabiner-Elements) `brew cask install karabiner-elements`
2. run the program, and install "Anti-RSI App Switch" config from the internet repo (or anything else you prefer):
Menu bar icon -> Preferences -> Complex Modifications -> Add rule -> Import more rules from internet -> search for "rsi" -> Anti-RSI App Switch -> Import (you may have to go through the "Add rule" a few times to enable all parts of the rule, but the internet import happens only once)
My only serious RSI experience was on Laptops, with the task switching combo - Alt+Tab (or Cmd+Tab/Cmd+`) - which was really killing my left palm with severe pain.
Since that time I'm remapping left-Alt/Cmd+Tab to left-Alt/Cmd+Spacebar (Karabiner on Mac, Sharpkeys+Autohotkey on Windows), and I'm constantly amazed how good and productive that combo is. And that it should have been used for computers instead of Alt+Tab from factory.
I'll share the configs gladly ofc if anyone's interested.
