The leading cause of this is using a keyboard layout other than the QWERTY Standard keyboard with your Mac.
If you use a non-standard QWERTY keyboard layout like a German or French keyboard, the keys you enter will differ from the standard QWERTY keyboard.
Example: Command + Y on the QWERTY keyboard, but if you are using a different keyboard layout, it would be a different command that is sent.
Also, the “+” key will be in a different location.
At this time, the easiest fix is to use a QWERTY standard keyboard layout.
Tool Tip: Some applications can compensate for this by allowing you to change the “hot-keys” used within the application. Please note this will be an application fix and not affect any other applications you are using.
Keyboard layout examples are listed below.
