I have to agree with Mark.  In my last job (I am retired now) I had to
make extensive use of the Alt-Tab feature.  Often it was to find (search
for) a browser window (organisation was stuck on IE 6), but where it
really came into its own was when switching between two applications.
My productivity would have been severely limited without that simple use
of the Alt-Tab feature.
