You can continue to check what keys are down in the background using
Revolution by using the keysDown() function or the commandKey() / other
function key functions.  I'm not sure what you would use this for, but it
can be done.  For example:

on mouseUp
  send "checkKeys" to me in 10 milliseconds
end mouseUp

on checkKeys
  put keysDown() into fld 1
  send "checkKeys" to me in 10 milliseconds
end checkKeys

Kind regards,

Kevin
