New: press Ctrl+Alt+M to open the chat window directly.
No more reaching for the system tray icon. Before, every chat meant moving the mouse down to the bottom edge of the screen, which dragged an auto-hidden taskbar into view (and into screen recordings). Now the keyboard brings it up and the taskbar stays hidden.
The hotkey only opens the window — it does not close it. Use the window's own X to close. This is deliberate: RegisterHotKey captures the combination globally, even while you are typing, so a toggle would swallow a half-written message.
If another application already owns Ctrl+Alt+M, the hotkey disables itself and the hint is hidden from the tray menu rather than shown as a dead entry.
