{{task|Terminal control}}[[Category:Terminal control]]

The task is to hide the cursor and show it again.

AutoHotkey

Keep in mind that AHK is not built for the command line, so we must call the WinAPI directly.

Befunge

Assuming a terminal with support for ANSI escape sequences, this hides the cursor, waits for the user to press ''Enter'', and then shows the cursor again.
