How do i Minimize all open windows

How do i Minimize all open windows at the same time.
(minimize them into the dock)

I dont want to use Expose to do it.. temporarily

running panther 10.3.3

the hide others command works better then the normal option command H

which just minimized windows in the current selected application.

so basicly there isnt anyways to minimize all windows. regardless of what app you are using

That only works in the application selected
what if you have 10 differnet apps open each with several windows

I want to be able to minimize all at the same time
