Frequently Asked Questions (FAQ)

How can I identify a faulty or chatter switch?
If a key remains stuck in active state or registers unprompted events, the mechanical switch is damaged.
Does it capture F1-F12 and modifier keys?
Yes, event listeners capture standard modifiers, function keys, and navigation clusters.
Are keystrokes logged or transmitted?
Zero keylogging. Keystroke events are handled strictly in local memory and instantly discarded.
