Description of Terms Associated with FilterKeys
SlowKeys - The sensitivity of the keyboard can be a problem, especially if you strike keys accidentally. SlowKeys instructs Windows to disregard keys that are not held down for a certain period of time.
RepeatKeys - Most keyboards allow you to repeat a key just by holding it down. If you cannot lift your fingers off the keyboard quickly enough, this can result in unintentionally repeated characters. RepeatKeys lets you adjust the repeat rate or disable it altogether.
BounceKeys - You may "bounce" keys, resulting in double strokes of the same key or other similar errors. BounceKeys instructs Windows to ignore unintended keystrokes.
Description of Tones Produced by the FilterKeys Shortcut Key
If you press down and hold the right SHIFT key for four seconds, you hear three short warning tones. No functionality is enabled with these warning tones.
If you hold the right SHIFT key for eight seconds, in addition to the previous tones, you hear a rising tone and the following default FilterKeys settings (or the last settings saved) are enabled:
-
RepeatKeys: On, one second
-
SlowKeys: On, one second
-
BounceKeys: Off
If you hold the right SHIFT key for eight seconds, in addition to the previous tones, you hear two rising tones and the following Emergency Level 1 FilterKeys settings are enabled:
-
RepeatKeys: Off
-
SlowKeys: Off
-
BounceKeys: On, one second
Holding down the right SHIFT key another four seconds (16 seconds total) produces three rising tones and invokes the Emergency Level 2 setting with the following settings:
-
RepeatKeys: Off
-
SlowKeys: On, two seconds
-
BounceKeys: Off
