--- Comment #1 from Peter Hutterer <peter.hutterer at who-t.net> ---
evdev's implementation (which dates back to the mouse driver, which dates
  back to the mists of time) has two functionalities:
  1) Button X locks button Y (usually X == Y)
  2) Button B locks the next button pressed
Googling shows a few public instances of X != Y, and a few instances of 2).

OS X doesn't seem to have that feature. Windows calls it ClickLock,
and has an extra setting to regulate how long the button must be held
before lock engages.
