By simply short-pressing the hotkey (less than 0.5 seconds), the recorder will lock, enabling you to speak freely without keeping the hotkey pressed.
Once you're finished, short-press the hotkey again to stop the recorder and begin the transcription process.
The push-to-talk functionality is still available and can be used by pressing and holding the hotkey for longer than 0.5 seconds.
This feature is enabled by default, but you can turn it off in the app settings if needed.
