Comment(by greenfox):

 My control key sometimes goes on (and sometimes stays on). The environment
 is warm and dry.

 The key stickiness on my keyboard seems not to be affected by bringing it
 inside (a warm dry house) from a cold garage. Neither was it a problem
 when using it in a cold car for about a half hour.

 In running the keyboard diagnostic, I have seen these keys stick: 'a',
 'i', 's', '1', ';' and most annoying, the control key. (The presence of a
 stuck key other than a modifier key (ctrl, alt, shift) would go unnoticed
 in actual use, and can only be seen in the keyboard diagnostic.) I have
 never seen my ALT key stick or activate by itself.

 The main problem is the control key sometimes comes on (and sometimes
 stays on) when the 'a' is pressed (sometimes it is another key that
 activates the control key--but I haven't seen this during the keyboard
 diagnostic test, only during actual use, and am not sure which key was the
 culprit).

 Pressing the stuck key once un-sticks it.

 While I can put up with this erratic behavior of the keyboard, I can
 imagine a 12-year old throwing the XO across the room the third time it
 happens!
