I wonder if there is a way the user can control the font size
in the .chm file from the viewer. I know you can go to your
internet browser and change the font size there, but this is a bit
convoluted. Is there a control available in the chm viewer that I
I'm not sure if CSS font sizes will override this or not.
Additionally, you may wish to try pressing and holding the Alt key
while rolling the mouse wheel (if you have one) as this sometimes
changes the font.
