Keyboard shortcuts cntrl ^ / in Wolfram Cloud

Hello, this may seem like a trivial question, but I am trying to use the keyboard shortcuts cntrl + ^ and cntrl + / in Wolfram cloud, such as 2 cntrl ^ 3 or 2 cntrl / 3, but it’s not working. I have a basic Wolfram cloud account, and I want to use these features to be able to format the input more compactly. I searched here →

but the shortcut is still not working.

Shortcuts like cntrl + ^ and cntrl + / only work for Mathematica and Wolfram Desktop I think (didn’t try it on the latter).

All the shortcuts for the Wolfram Cloud should be listed here:
