I have a presentation (a countdown timer) with 300 slides. Is there any way
to change the font and size on all the slides at once instead of going
through each slide and changing each text box manually?

Here are a couple of things to try:

(1) If all the text is in placeholders, you can go to the slide master
and change the font there.

(2) Try going to the Format menu and choosing Replace Fonts. This should
work if you just want to change the font face, not the font size or any
other characteristics.

(3) If all else fails, a VBA script could be written to adjust the font
of every shape with text.
