Untrap = Middle Button --> ALT-TAB allows the middle button on your mouse to act like ALT-TAB, switching focus away from the WinUAE emulation. This is useful because WinUAE traps the mouse-cursor within its Window borders, and if your hand is already on the mouse and you want to escape this capture, you can just press the middle button.
Show GUI on startup will allow you to double-click a .uae config-file without it immediately launching the emulation.
Use CTRL-F11 to quit Just press this key combination to quit WinUAE. If this option is enabled, the ALT-F4 combination can be used by the Amiga properly, and CTRL-F11 will quit WinUAE.
