I'm using Mac OSX Yosemite 10.10.4.
I'm trying to use the shortcut
option + command + left arrow for Spectacle, but I'm getting an error that claims the shortcut is already in use. I can't figure out where it's being used. I checked System Preferences > Keyboard > Shortcuts, but don't see it in use anywhere. Is there a way for me to search for the shortcut?
