Layout Mode keyboard shortcut disappears
Operating system version
Mac OS-X 10.9.1
Description of the issue
On my MacBook Pro, I have noticed that from time to time, in FileMaker Advanced 13, the keyboard shortcut for Layout Mode disappears.
The menu command for Layout mode still works. The toggle in the lower left corner of the window still works. Only the keyboard shortcut is disabled, and the symbol for it in the View menu is also gone. This happens in a Starter Solution where there are no custom menus.
Not sure what makes this happen. But if I quit the application and restart it, the menu command with the keyboard shortcut re-appears.
Steps to reproduce the problem
Sit next to me for a few hours.
typing command-L will enter layout mode,
