Differentiate between left / right cmd key?

[aydoo]

Is there any way to e.g. only listen to the behaviour if the right cmd key is pressed? Specifically, I'd like to only use arrow keys when pressing right-cmd + h/j/k/l. left-cmd interaction should be ignored.
I couldn't find any information regarding this unfortunately.

This should help:

1. If you are listening for key events of right command and want to modify next key presses if it is pressed:

   1. http://www.hammerspoon.org/docs/hs.eventtap.event.html#getKeyCode
   2. http://www.hammerspoon.org/docs/hs.keycodes.html#map

2. If you are listening for key events of some keys and want to check if right command is pressed:

   1. http://www.hammerspoon.org/docs/hs.eventtap.event.html#rawFlags
   2. http://www.hammerspoon.org/docs/hs.eventtap.event.html#rawFlagMasks
   3. hs.eventtap.event.rawFlagMasks has incorrect documentation about device keys #2375

I wanted to say that when I asked the same question, someone told me to put the word "right" before "cmd"
so I tried:
hs.hotkey.bind({"rightcmd"}, "t", function()

but it actually binds for left command and right command , so it doesn't work. Is there a bug report for this? or will this be fixed?

How am I supposed to do it?

is this bug in track?

What is track?

See #1199, specifically #1199 (comment) for why it's hard and #1199 (comment) for a proposed experimental workaround.

There is also a spoon ready to be merged implementing the workaround but I haven't had the time to do so yet.
