[macOS Sierra, FM v16]
Since Filemaker version a-long-time-ago, I have used a shortcut based on an AppleScript to go to the next layout. The script looks like this:
tell application "FileMaker Pro Advanced"
go to layout after current layout
I have assigned this to a schortcut (CTRL+ALT+ Arrow up/down).
As a developer, this is extremely convenient, you don't need to enter Layout mode to go to the next layout.
However, in FM16 this is not longer possible. What's up with that?
