I have recreated some shortcuts to integrate them in the logic I have used for the ones I have created for commands which didn't have one at all.
My workflow benefits from the homogeneity. Easier to remember. Shift+Ctrl are common for all.
Shift+-Ctrl+S for Score Manager, Shift+-Ctrl+O for document Options are easier to remember than the ones Finale suggests.
I know about the System Preferences method, but It is unpredictable on my set-up. The shortcuts I have defined for 25 suddenly appear as 2014.5, and some don't work at all. MakeMusic support couldn't explain why, and won't guarantee that these shortcuts (System Preferences) will work on a non-US MacOS and keyboard....
Keyboard Maestro is much more consistent and reliable.
