I undoubtedly have clicked something, in code editor it is replaces my code or text when I type instead of inserting it, how do I change this? (Version 12)

Thanks,
Kent

Make sure you have a space before the code you are trying to enter. So if you are adding something to a css rule like body { color:#fff } make sure your cursor is not sitting on the C in color. Because if it is the Editor thinks you want to replace color with what you are typing.

Kent,
The "Insert" key on your keyboard acts as a toggle between "Insert" and "Replace". If you inadvertently pressed it and ended up in "Replace" mode, just press it again and you'll be back in "Insert" mode.

Oh, my bad. I thought you were talking about Auto Completion. That is my brain fart for the day.
