If we hadn't supported floats yet, we could have hacked that in ;-)

Maybe, for zoom, if the value has a percent sign, we do the math for
them?  So, SetValue(Zoom,400%) does the right thing?

True, but this came up because someone wanted the zoom menu to reflect
reality, so you'd have to figure out the numbers anyway to fill in the
menu buttons.

Of course, if you wanted to be really flexible, you'd support
generic math operations in values:

	SetValue(Zoom, 1<<5);
