I'm unable to enter the Command + or Command - into the keyboard shortcuts. These are the Zoom in and Zoom Out keyboard shortcuts. The Zoom IN/OUT for Logitech is WRONG. Further, I should be able to enter the Command > and Command < for keyboard shorts - because the Forward / Backward options in Logitech do not WORK correctly. Please fix these silly things, of forward / backward and Zoom in / Zoom out to match the keyboard shortcuts. DO NOT try to re-invent the wheel.
