When you have a Braille input keyboard enabled on the main computer keyboard, Braille characters are never repeated automatically, just one character is typed per press.

However, keys that are enabled and are not part of the Braille key layout will by default behave according to the Windows keyboard settings. This means that keys such as Escape and Tab will auto-repeat unless Windows filtering is enabled, as will the standard typing characters if you have the main keyboard enabled as well as Braille input, or have specifically enabled some keys.

You can suppress this repetition with the "R" option (uppercase) in the Braille input driver configuration substring. Then any standard keys will, like Braille characters, only activate once per press. This setting is off by default, but can be explicitly turned off using the "r" option (lowercase).

The capability to have WTC suppress key repeats is provided as a convenience. Because it is part of the Braille input setup, it can be effective only when WTC is the active application, or it can be active globally. You can enable it without actually configuring Braille keys using the special mapping features of WTC. If you want to use the more sophisticated Windows key filtering accessibility options for general purposes, it is advisable not to enable the WTC feature at the same time.
