Inputs stay in this tab and are not uploaded or saved automatically. Optional aggregate usage counts and coarse processing diagnostics are sent only after consent, without input content or filenames. Clearing or closing loses inputs; save needed outputs first.
Method and limits
Start and focus the observation area. Only the keys currently held are shown (key, code, repeat and modifiers, up to 32). Releasing a key, losing focus, pressing Tab or Escape, or hiding the tab clears them. There is no keystroke history and no export; keys reserved by the OS are UNKNOWN. This is a local browser observation only: no hardware diagnosis and no universal accuracy. Nothing is stored, recorded or uploaded, and no private-data telemetry is sent. Stop or reset clears the session. Browser, OS or permissions may leave results UNKNOWN.

How can I check the current result?
Press and release one key while the area has focus. Its row should disappear when you release the key, and Stop should clear the current list.
