Hello, help a newbie out!
Is there a way to add text to a cell with existing text without using the mouse?
I am used to pressing “enter” and it opening the highlighted cell so you can add text without overwriting. Is there a way, EXCLUSIVELY with the keyboard, that you can add text to a cell that already contains text?
This is driving me up the wall, as I couldn’t figure out how to phrase this to google or find anything in the help forum
