Keyboard input/Flush the keyboard buffer
var k = frequire('Term::ReadKey');
k.ReadMode('restore'); # Flush the keyboard and returns input stream to initial state
# ReadMode 0; # Numerical equivalent of keyboard restore (move comment marker to use instead)
# A more complete example for use in keyboard handler programming.
# We should also check we are being used in an interactive context (not done here).
k.ReadMode('cbreak');
# Flush the keyboard in terminal character break mode
while (k.ReadKey(-1) != nil) {
# Do nothing
}
# Don't forget to restore the readmode, when we are finished using the keyboard
k.ReadMode('restore');
