in thread The most useless key on my keyboard is:

They don't appear to do anything in any of the apps I use.

Exactly. This leaves it free as a modifier for custom mapping. Under Windows, there are some defaults (Win-L locks the display, Win-D shows the desktop, etc.), and there are third-party apps that let you map it to do more. I use one called WinKey (which isn't made anymore, sadly). When I want my browser up, Win-W. Win-P begins an Eclipse/EPIC session with a blank .pl file. And so on.

In Linux and BSD, they key is assignable to window-manager tasks (as the modifier 'Hyper' in most cases). On my linux devel box, Win-D starts my development environment (Eclipse/EPIC, Devel::ptkdb, and a couple other tools).

On the Mac, it's basically the PC world's "control" key, so almost all apps use it.

But, on any PC-based platform (damn it, I can't say 'x86-based' anymore!), it's one of the most useful keys because you can make it do whatever you want.

ScrollLock, though... what a pointless key. (Keyboard holy war! Yay!)

    If I have just text terminal (e.g. when admining some server) and (forgot|didn't mean) to pipe command to 'less' and the output took more than one screen it's the only way I know to scroll the screen up.

      On linux, Shift-PgUp/PgDown works for me in most terminals, including the console

        If you press ctrl-s it will stop the terminal from scrolling so you can use shift-pgup/pgdown without the terminal scrolling ahead. Press ctrl-q to un-lock the terminal.

        Your terminal program might not jump down after you press shift-pgup. I'm pretty sure aterm jumps ahead. It might even be a setting somewhere.
