You've already received some number of solutions that should all work.
If you decide to go with the low tech route, here's how I accomplish
what you want to do; given my preference for low-tech it works very
well.
Before you start the presentation and without the audience in the room:
* Open IE (or whatever web browser) and have it set the way you want.
* Open PP and start the slide show so that it is on the first slide you
want the audience to see.
* Use ALT+as-many-TABs-as-necessary to switch to IE. Now, use ALT+TAB
to switch back to the slide show. Every subsequent ALT+TAB will toggle
between the slide show and IE.
Note 1: There will be two icons for PP -- one for the PP program and
the other for the slide show window. You need to select the slide
show.
Note 2: The sequence in which ALT+TAB shows the available icons changes
based on previous selections and the state of the respective windows.
So, after you switch to IE and back to the slide show using ALT+TAB,
each future ALT+TAB will toggle between those two.
Note 3: Using ALT+TAB does show all the choice icons in the middle of
the monitor / projection screen, but if you do the switch fast enough
it is only for a split-second.
