I cannot input superscript with the keyboard shortcut ctrl-6.
I am on mac osX 10.14.5. The menu button in insert>typesetting>superscript works and says the shortcut is ctrl-6. One site said use ctrl-6; another site said use ctrl-^. Other shortcuts like control-7 (above) and ctrl-minus (subscript) work. I have tried control and command with different combinations of shift and various numbers. No luck. I haven't edited any Mathematica setting files.
