The Windows client runs from the tray, keeps the global hotkeys registered, and only shows the settings window when you need it.
Settings mirror the real app: microphone choice, feedback volume, API key entry, and custom dictionary terms for words the transcription mishears.
Ctrl+Shift+V records and stops. The transcript is always copied; if the cursor has not moved, WavType also pastes it for you. Ctrl+Shift+X discards.
