Flit Extra layout is an extra keyboard layout plug-in designed specifically for Flit Keyboard. This free plug-in requires Flit Keyboard version 2.5 or above and can be easily accessed by selecting the 2nd keyboard option from the Flit Keyboard settings after installation.

With Flit Extra layout, users can now input keys that are normally missing from other software and hardware keyboards. It is compatible with any application that follows the Android keycode standard, including popular apps like AnDOSBox, AnUAE4All, and AnVICEx64.

The plug-in offers two layouts to cater to different user needs. The first layout is the "Special keys layout," which includes essential keys such as Ctrl, Alt, Shift, Esc, Tab, and even function keys F1 to F12. However, it is important to note that due to Flit Keyboard's current limitation, Ctrl, Alt, and Shift cannot be used as modifiers.

The second layout is the "Gamepad layout," which features a D-pad and A, B, C game keys. This layout is especially useful for gamers who want to have a gamepad-like experience while playing games on their Android devices.

Overall, Flit Extra layout is a valuable plug-in for Flit Keyboard users who want to enhance their typing and gaming experience. It provides additional key options that are not commonly found on standard keyboards, making it a versatile tool for various applications.
