I had Sig send me one and really like it, the format on my machine requires funky key manipulations of the screen content to enlarge it, but once I figured that out, it was pretty cool and informative.
Just checked it out, you click the lower left "grey" area under the left menu, and then push Cntl and + to expand the window so that you can read the slide, and then Cntl and - to go smaller to run the menu.
