I am using Macbook Air Mid2012 with El Captian 10.11.3 version.
I have two languages installed (two input sources). Currently my shortcut to toggle the language input is "CMD + space." I would like to use the option key on the right-hand-side as a shortcut for input source toggle.
System Preferences - Keyboard - Shortcuts - Input sources won't allow me to specify option key alone as a valid shortcut.
Is there anyway to do this?
Thank you!
