Doesn't seem to be one for XP...

If anyone is wondering, like me, why a particular key combination doesn't work they'll find the answer on this page.

Strangely, I never knew that CTRL+SHIFT+N creates a new folder in explorer. Always bugged me that (I use the excellent Directory Opus on my main machine, but very useful for servers!).

Cheers,
