I got a new laptop in February, upgrading from OSX 10.9.5 to 10.14 (Mojave). Unfortunately, many of the keyboard shortcuts don't work, including Search Notes, Strikethrough, and Copy Note Link. I've gone into Keyboard > Shortcuts in System Preferences to manually adjust these, but no matter what I do, the shortcuts either don't register, or trigger another action (e.g. creating a new note or copying the public link). Even using the default shortcut (e.g. for Search Notes) doesn't trigger the action.
Can anyone provide guidance for what I might try?
