De Graaf DATIX, Inc. Hendersonville, NC > dad@xxxxxxxxxxxx www.datix.us You must have forgotten how unnatural those keystrokes were when you first learned them! I am learning them now (I take upon myself to learn and use vi), but I still get confused every now and then. For my (vanilla vim) install, u is NOT up a page, rather it is undo. So whatever you call standard is probably better called "what David is used to". The logical reasoning behind the current firefox key combos is the fact that most firefox users are running you-know-which OS and for them (they think that vi means 6) the 'standard' up key is marked with an up arrow. Firefox developers rightly chose uniformity across platform versions, and gave the same key combination to linux and mac platforms. Anyone who doesn't like it, can change it. Yes, it is a pain to change it, but so was configuring my pptp internet connection. Or, for that matter, so was learning the vi keystrokes!
