Keyboard shortcuts not working
I want to create customized keyboard shortcuts so that I can open applications like Messages and Safari with the click of a few buttons.
I went to:
System Proferences > Keyboard > Keyboard Shorcuts > Application Shortcuts
I pressed the + button and selected Messages from the drop-down menu, then made my shortcut:
Command + Shift + M
However, when I'm on my desktop, the shortcut does not work. It only works when I already have Messages open as my ACTIVE window. I press Command+Shift+M and Messages will disappear, similar to what happens when you press Command+H to hide a window. Unlike Command+H, however, when I press Command+Shift+M again, Messages will reappear. Same thing happens if I minimize Messages using Command+M first.
Why is this happening? I just want to be able to open Messages (by clicking Command+Shift+M) while I'm browsing Safari or something.
