oh! sorry -- i was mis-remembering. you're correct that i
previously recommended that the last element should be 1, and
that's still correct. (although in practice greater values
probably won't be much different).
forget what i said in my previous mail -- if you think the
acceleration is too slow with "xset m 7/4 1", then adjust it by
changing the first parameter: "xset m 2 1", or "xset m 9/4 1",
or "xset m 5/2 1". remember that that parameter is a fraction.
(which is an odd choice -- i probably would have used a
be sure and also test with an activity that requires very fine
motor control. some of the etoys games, where small pieces need
to be connected together, are a good example.
