Nice post. Here are some of my additions:
Global
Shift+Delete -- permanent deletion without going to Recycle Bin
For any text
Ctrl+Shift+Left -- decreases highlighted text one word (keep hitting the arrow to highlight successive words)
Ctrl+Shift+Right -- increases highlighted text one word
Shift+Home -- highlights text from cursor point to beginning of line
Shift+End -- highlights text from cursor point to end of line
Internet Explorer
F11 -- super maximizes window and also makes the URL field reappear even for windows without the URL bar (like for flash pop-ups for example).
Home -- goes to top of page
End -- goes to bottom of page
Esc -- stop page loading
Backspace or Alt-left -- navigate one page back
Alt+right -- navigate one page forward
Page Up -- scroll one page up (duh

)
Page Down or Spacebar -- scroll one page down

Not purely a kb shortcut, but what I do is right-click -> New -> then hit 'f'. It's a tad bit faster than using the mouse to selecting Folder.

But yeah I think it would be much more convenient if Windows had a ctrl-N function for that in My Computer or Windows Explorer but oh well.
