Hotkey for highlighting sentence cursor is in conflicts with MacOS hotkey to type em dash

The plugin's hotkey "Shortcut for highlighting sentence cursor is in" uses the same key combination as the default MacOS way to type an em dash (—). This confused me until I figured out what was happening; then it was easy to work around by deleting the hotkey. 

Ideally you should pick another key combination (I understand picking them is hard), or not assign a hotkey by default.
