I can't type because of this annoying cursor.
go to settings (look on your left to see the round bumpy circle). then look for keybinds. Once you find it, click it, and change it to default.
done. You are all set.
You are in the Vim mode. To start typing, type
i, then to exit the typing mode, type Esc.
And also, how do you do that? Just curious.
