/* Old Macs have no key repeat, newer ones have fully working one.
The ones inbetween when repeated key generates an escaoe sequence
only the escape is repeated. With this workaround however a fast
e.g. down arrow-ESC is perceived as down arrow-down arrow which is
also annoying but is less so than the original bug of exiting from
the current window on arrow repeat. To avoid unaffected users suffering
from this workaround match only exact models known to have this bug.
