Questions tagged [arrow-keys]

The up, down, left, and right keys on a keyboard, also known as "cursor keys".

The arrow keys are the up, down, left and right keys on a keyboard, also known as "cursor keys". They are primarily used to move the cursor around on-screen text, and are also often used to move player characters in games.
