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
QWERTY studies administered by Dvorak himself before and after World War II. Economists Stan Liebowitz and Stephen Margolis have noted that rigorous studies are inconclusive as to whether they actually offer any real benefits, and some studies on keyboard layout have suggested that, for a skilled typist, layout is largely irrelevant – even randomized and alphabetical keyboards allow for similar typing speeds to QWERTY and Dvorak keyboards, and that switching costs always outweigh the benefits of further training on whichever keyboard you already use. The most widely used such alternative is the Dvorak Simplified Keyboard; another alternative is Colemak, which is
