Really I'm just trying to use the Ctrl+2 shortcut to make a radical, but for some reason this won't work. What could possibly be going wrong? The exponent shortcut works (i.e. Ctrl+6).

$\begingroup$ What OS version? Do you have Spaces enabled? $\endgroup$– Brett ChampionJan 28, 2013 at 20:21

$\begingroup$ It work here, Mma 9 & OS X 10.8, US English kb layout. What language keyboard layout are you using? What keyboard shortcut is listed next to the menu item Insert -> Typesetting -> Radical? Does that menu item work? Did you ever edit any files inside the Mma installation directory? $\endgroup$– SzabolcsJan 28, 2013 at 20:21

$\begingroup$ Have you tried Ctrl+@? On my keyboard the @ is over the 2. Can you try to use the number where the at is? $\endgroup$– halirutan ♦Jan 28, 2013 at 20:25

1$\begingroup$ @relatively: en.wikipedia.org/wiki/Spaces_(software) which still exists, though is exposed a bit differently now, but which uses/used keyboard shortcuts that could overlap with ones used by Mathematica. $\endgroup$– Brett ChampionSep 21, 2021 at 22:22

Converting my comment to an answer. On my OSX machine Ctrl+2 worked, so I checked the documentation which states under Details and Options
In my keyboard layout the 2 is the same key which is used for the @. Maybe on your machine this differs. Can you try to use Ctrl+@?

$\begingroup$ I have almost the same problem: NONE of the control sequences work on my mac, in the cloud. Wolfram just beeps at me when I try to use them. The weirdest thing is, I faintly remember I was able to use them at an earlier time. I have an american keyboard, I checked keyboard shortcuts in System Preferences (almost all are disabled, and none of them were any of the ones that mathematica uses). $\endgroup$ Sep 21, 2021 at 18:35
