David, the shortcuts modifier in MacOS distinguishes between modifier keys and the rest of the keyboard. You typically can’t use a combination of only modifier keys as a shortcut ( Control, Command, Option and Shift). You need to combine a modifier key with another key like ‘Control+1’ or ‘Command+u’. Also be aware that MacOS and Figma is already using a lot of the available shortcuts, so try to test what you want to use first, to make sure that combination does not already perform an action in Figma or MacOS. Good luck p.s. I’m not sure what you mean by navigator version, but if you mean Figma in browser, no, I believe the shortcuts won’t work there.
