This kind of human error is usual enough even outside computer world to have been given a term that's made it's way to the mainstream English. From Webster's Encyclopedic Unabridged Dictionary of the English Language (Gramercy Books, 1989):
:typo: n. pl -pos. Informal. See typographical error [shortened form]
:typographical error: an error in printed or typewritten material resulting from striking the improper key of a keyboard, from mechanical failure, or the like.From Jargon File 2.9.8, 1 Jan 1992:
:mouso: n. [by analogy with 'typo'] An error in mouse usage resulting in an inappropriate selection or graphic garbage on the screen. Compare with thinko, braino.If you make a typo (or "clicko"), you should ask for the undo immediately or sooner. Indeed, some experienced players, when suspecting a typo, pause for a few seconds in case the opponent asks for undo, and sometimes even ask "typo?". This typically means they are prepared to undo the move then and there, but won't do so after they have made their move, and so it serves as a control of the typo requests.
People who receive requests for an undo are under no obligation to grant them. However, in keeping with the friendly spirit of IGS, granting undos for accidental clickos and typos is considered to be sportsmanlike, and good polite behaviour besides. If you insist on following a policy of never granting undos, you should probably say so before starting the game, and putting a sentence to that effect into your info is a good idea.
If you ask for an undo because you misread the
board, did a stupid blunder, or had a moment of insanity,
don't expect anything.
