These functions return the value of any key which is pressed down when the INKEY function is used, or has been pressed since the previous INKEY/INKEY$. The key is returned as either its ASCII value (INKEY) or its character (INKEY$). INKEY returns -1 if no key is pressed. The ASCII value is the numeric value associated with each key by the computer. INKEY$ returns a blank string if no key has been pressed.

Note The function only works when the cursor is in the text window. Click the cursor in the text window before pressing a key.
