Application keypad (DECKPAM)

Category: modes · Tags: DEC Private Modes, VT100 · Specification ↗

DECKPAM switches the numeric keypad to application mode, where numpad keys send escape sequences instead of numeric characters. Enable with ESC =, disable with ESC >. This allows applications to distinguish numpad keys from the main keyboard number row.
