The core protocol allows only control over whether or not the entire keyboard or
individual keys should auto-repeat when held down. RepeatKeys is a boolean
control that extends this capability by adding control over the delay until a
key begins to repeat and the rate at which it repeats. RepeatKeys is coupled
with the core auto-repeat control: when RepeatKeys is enabled or disabled, the
core auto-repeat is enabled or disabled and vice versa.
Auto-repeating keys are controlled by two attributes. The first,
timeout, is the delay after the initial press of an auto-repeating key and the first
generated repeat event. The second,
interval, is the delay between all subsequent generated repeat events. As with all boolean
controls, configuring the attributes that determine how the control operates
does not automatically enable the control as a whole.
XkbGetAutoRepeatRate queries the server for the current values of the RepeatControls control
interval_rtrn with them, and returns True. If a compatible version of the Xkb extension is not
available in the server
XkbGetAutoRepeatRate returns False.
