I noticed a new warning in Event Log: "Shortcuts conflicts
Extend Selection and 11 more shortcut conflict with macOS shortcuts. Modify these shortcuts or change macOS system settings."
I click Modify Shortcuts and get this window:
I have the options at the bottom Set DEFAULT, Accept Left Side, and Shrink Selection... however, I'm not seeing what the "Left Side" is nor what exactly these options will do. I'm afraid of clicking any of them at the moment.
