I learned an important lesson today: many apps have a few internal shortcut preferences that can be set in that app’s preferences (and then perhaps forgotten by you). They can then “cryptically” interfere with other shortcut-related software, in particular:
- MacOS Services preferences
- MacOS Keyboard shortcuts
- Keyboard Maestro macros
- TextExpander macros
Takeaway: don’t set shortcuts during app installation if you don’t intend to use them! If you forget one of those shortcuts, it may haunt the functioning of your future macros.
