redo button has never worked in android studios?

Question

i have found that android studios has never contained any way of 'redoing' a text edit (the opposite of ctrl+z)? the option exists in the menu/ toolbar but is greyed out. it always has been and it has never functioned. to test, i have created a clean, empty project, typed in the java class, moved the cursor to elsewhere in the class (incase back to default for some reason prevents it working), typed again. i then have tested both ctrl+z and manually clicking the undo button, but i am simply NOT ABLE to use the 'redo' option at all. not once since i have been using this IDE.

can ANYONE please explain this behavious and how to get this functionality back? as im finding i often undo one step too many and forget what ive just destroyed. thanks

Go to File -> Settings -> Keymap
On the right side of the screen, search for "redo" and right-click on the Redo option. Add a keyboard shortcut (I use ctrl+Y which is pretty standard across applications).
