If you use Emacs in or for your presentations, here’s a nice tip from Robin Green on how to scale all the windows up for better presentation:
#Emacs Of The Day: Running org-mode on a 4K projector, you scale the buffer but the modeline stays tiny? zoom-frm.el maps C-x C-+ to scale all windows in the frame plus modelines. (n.b. requires packages frame-cmds and frame-fns)https://t.co/HJLzqQc5Fh pic.twitter.com/iYddBEHLHO

You’ll have to load Drew Adams’ zoom-frm.el but if you give a lot of presentations where Emacs and its buffers play a significant role, you may find it worthwhile and helpful.
