Any key
Updated: 12/31/2020 by Computer Hope

Any key is any of the keys on the keyboard such as the spacebar or Enter. When a program gives the prompt "Press any key to continue," this indicates to press any of the keys on your keyboard to continue. Keep in mind that there is no computer keyboard key labeled "any key."
Tip
When you're unsure what's highlighted, we recommend using Esc as the any key. If a program or program option is highlighted and you press Enter or spacebar it may activate or execute the highlighted program or option. For example, if the computer monitor is asleep you can press Esc to wake it up.
