Other Updates for Karabiner:

• Enable "Application Key to Option_R (right option key)"

Change Log

• Nov. 17, 2014
  • Updated to support both left and right alt keys.
• Nov. 18, 2014
  • Updated to only do this for both Parallels and when using my Microsoft Natural Ergonomic Keyboard. I want the internal MacBook Pro keyboard to still behave the same way.
  • Note that you'll want to use Karabiner's EventViewer to determine your device's specific vendor id and product id (see docs for more details).

You seem to understand this quiet a bit. Would you be able to help me with the problem I am having?
I want to remap the WINDOWS key to the ALT_LEFT key (if possible ONLY for my windows keyboard, if not profiles are fine).
Thing is that the command and alt key on mac are reversed on a windows keyboard. I would like to start coding with my mechanical keyboard (which is the windows layout). This is with removable keycaps, so when I would start working I would simple switch the two keycaps.

BTW: this is what I have now, but it is not working.. (also dont know how to check if this is 'active').

Thanks

@NicolasVanhecke my apologies, but I never was notified of your comment, otherwise I would have tried to respond!

I'm not sure off hand what might be going on with your problem, but I will say that, if you're on MacOS Sierra, Karabiner doesn't work any more and you'd need Karabiner Elements instead. That's actually what I'm using now and it has a GUI for mapping keys per device (which is a relatively new feature). It's a lot easier than messing with the private.xml file.

Regarding notifications... oh. This is why - isaacs/github#21. 🤦‍♂️

See latest Karabiner Elements support to give me all of these options at https://github.com/drmohundro/dotfiles/blob/master/config/karabiner/karabiner.json.
