If you use an Aero theme, there should be a "handle" at the right
end of the Windows taskbar that you can either hover over to
momentarily see the desktop (unless you disabled Aero Peek) or
click on to toggle between the desktop and app windows.

Alternatively, right-click on an unused spot on the Windows
taskbar and select "Show the desktop". To toggle back,
right-click again on the Windows taskbar and select "Show open
windows".

Yeah, I know about the little button, but I want to do it without
moving from keyboard to mouse. Also, the button is inconveniently
small. I didn't know about the right-click taskbar thing, though. It's
not what I'm looking for, but it's maybe better than the button.
Thanks.
