Logitech R800 with Skim-app on MacOS 10.8

03 July 2013

I just acquired a Logitech presenter (a remote control just for presentations). It’s advantages over the Apple remote control are the built in laser pointer and buttons that can start/stop your presentation, advance and go back a slide, and to turn the screen black.

So far so nice, but when I want to export buffer contents to HTML using htmlize-buffer to post it here, I get the same light on black which seems incompatible with the design of this blog.
