I remember there was a way to toggle between "relative construction methods" perpendicular and parallel by pressing "P". I can't manage to do this any more. Is there a way to reactivate this shortcut?
In the Work Environment > Shortcut Schemes > Keyboard Shortcuts > List: All Commands by Scheme > Actions > Parallel/Perpendicular, assign the keyboard shortcut. Then Redefine your Shortcut Scheme to save the change.
