trigger zoom in/out on a big slide
I have a big slide trying to show a really big diagram. Font has to be pretty small to fit.
I'd like to create four zoom buttons -- one in each quadrant. You can click a button, and it initiates a zoom to that quadrant. Click again to zoom back out.
Ideas on how to implement? I'd really prefer not to create duplicate slides, if possible... but I'm looking for options. Thanks!
