Romanian keyboard layout Since Romanian hardware keyboards are not widely available, Cristian Secară has created a driver that allows the Romanian characters to be generated with a US-style keyboard, in all Windows versions previous to Vista. It uses the right AltGr key modifier to generate the characters. An alternative, more ergonomic (though non-standard) keyboard layout, with a user choice between cedillas and commas, is proposed and implemented for the Microsoft Windows operating system by the Ergo Romanian project. They suggest altering keys on the standard QWERTY layout which are less frequent in Romanian, namely q, w, y, k, x, to produce Romanian characters
Fn key Fn key in Mac OS X. Fn is a modifier key, and works like other modifiers keys, such as Ctrl, Shift, Alt and AltGr. For a standard modifier key, the microcontroller inside the keyboard sends a scancode for the modifier itself, which is then interpreted by the operating system and combined with other simultaneous key-presses. The Fn key is a form of meta-modifier key, in that it causes the operating system to see altered scancodes when other keys on the keyboard are pressed. This allows the keyboard to directly emulate a full-sized keyboard, so the operating system can use standard
