Re: Disable Firefox's Command-Arrows page jump shortcuts

This hint is not really needed. The author is using the wrong key commands. You shouldn't be using CMD-Arrow to move around in text boxes.

"Wrong" says who? Cmd-Left Arrow has always moved to the beginning of the line (and Cmd-Right Arrow to the end of the line) in the "classic" Mac OS and in Mac OS X.

There's no reason why users shouldn't expect standard Mac OS X key bindings to work everywhere; this is clearly a bug in Firefox.

Thanks for that great link to the Apple Human Interface Guidelines.

I assume that holding down Fn on small Apple keyboards, while pressing Left Arrow or Right Arrow, will in fact send a program the keycodes for Home and End just as the key labels show. In other words: I assume programs do not need to detect Fn themselves. This makes me wonder why even Apple's TextEdit does not follow the guidelines for those keys...

Home, End

Pressing the Home key is equivalent to moving the scrollers all the way to the top and to the left. In a text document, for example, pressing Home scrolls to the beginning of the document; in a spreadsheet, it may scroll to the beginning of the spreadsheet or to the beginning of a row. These keys should also work in scrolling lists to display the top or bottom of the list.

End is the opposite of Home: It scrolls to the end of a document.

If the beginning or end of the document is already reached, pressing Home or End produces a system alert sound. Pressing the Home or End key has no effect on the location of the insertion point or selected data.

I also find it odd that Apple has introduced new keyboard layouts on 2nd or 3rd generation MacBooks and the aluminum keyboards, using F3 for Exposé and F4 for Dashboard -- while the guidelines still only mention F9-F12 as being reserved.

And finally, I never understood why Apple cannot sell the US keyboard layout in Europe -- not even when specifically asked to do so. I know, layout and keycodes are not the same thing. But here in the Netherlands we get a very tiny Return key, and an odd location of the backtick, to the left of the Z-key.
