[Legend has it][DT] that Undo was a key on early keyboards, starting
with Xerox Star, later Xerox Docutech, Sun Type 4/5/6/7.


Modern mass-produced keyboards do not have an Undo key.

If you are building a custom keyboard based on TMK or [QMK] firmware,
you can turn any key into Undo by assigning the KC_UNDO key code to
it. Be aware that some modern software will ignore it even if they do
have a notion of undo and handle Ctrl+Z.
