I’m having an issue with Scrivener not recognizing shortcuts that are assigned in the System Prefs. For example, I have a shortcut assigned to “No Style” in my macOS System Preferences under Keyboard>Shortcuts>App Shortcuts>Scrivener (see screenshots) but sometimes Scrivener doesn’t recognize it. This is not always the case, sometimes it does work, and it also doesn’t happen with all Shortcuts. It specifically happens with the “No Style” command. In the screenshot, the Shortcut for “Block Quote”, for instance, always works without problem. Unfortunately, I haven’t figured out what exactly causes it so I can’t provide step-by-step instructions yet.
But I’m wondering if anyone else has experienced this or might have some suggestions for where I should start digging. (Restarting Scrivener doesn’t help, I tried that already.)
BTW, I’m quite hesitant to use the “bug” tag, as I don’t know whether this is a Scrivener issue at all or some macOS quirkiness (doesn’t happen with any other apps, though) … so please if this doesn’t qualify as a bug, forgive me and the moderators should remove the tag.
