Can't name a macro

I select new macro in key commands. Dont get a way to name it!?? Just shows a “new macro”. spent 45 minutes trying to name the macro. (first time trying to make one) feeling stupid.

Like most name fields in Cubase you should be able to double+click on it and change the text.

I can’t tell you how many times I double clicked and NOTHING happened. Tried it just now and it worked! Feeling a little sheepish. Many thanks
