A user with very limited vision keeps typing whole sentences in capitals because they cannot see the Caps Lock indicator on the keyboard. Which accessibility feature plays a sound whenever a locking key such as Caps Lock or Num Lock changes state?
LPIC-1 Exam 102-500, objective 106. User interfaces and desktops easy
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
The options
Correct Toggle Keys
Correct. Toggle Keys gives audible feedback when a locking key changes state, so the user hears that Caps Lock has gone on or off without needing to see the indicator LED.
Not correct Sticky Keys
Wrong. Sticky Keys latches a modifier such as Shift or Ctrl so it stays in effect for the next key press, which helps a one-handed typist. It gives no feedback about locking keys.
Not correct Bounce Keys
Wrong. Bounce Keys ignores a second press of the same key that arrives within a short interval, which suppresses accidental double letters caused by tremor.
Not correct Slow Keys
Wrong. Slow Keys requires a key to be held down for a configured period before it registers, so that keys brushed in passing are discarded.
Why
The keyboard accessibility set is best learned as five distinct behaviours: Sticky Keys latches modifiers, Slow Keys demands that a key be held before it counts, Bounce Keys ignores a rapid repeat of the same key, Repeat Keys governs whether and how fast a held key auto-repeats, and Toggle Keys makes a sound when a locking key changes state. Each answers a different motor or sensory difficulty, and exam items name the difficulty rather than the feature.
