MacOS screen annotation/presentation software

I was going to write a little application to let me annotate my MacOS screen during presentations, but the Ink2Go product looks like it does exactly what I was thinking. As I’m creating a video presentation, such as when showing how to write some Scala or Android code, I want to be able to draw on the screen, such as writing text, arrows, circles, and boxes to highlight parts of the screen. Ink2Go looks like what I want.

LaTeX soul - How to highlight text in a LaTeX document

Summary: Use the LaTeX soul package to highlight text in a LaTeX document.

Suppose you want to provide a highlight color or background color for text in a LaTeX document. A good example is when you want to highlight the background yellow, so it looks like it was highlighted with a marker, to catch a reader's attention. "How do you do this in LaTeX?" you ask.

Normally I like to answer "simple", but in this case there is a multi-step answer. It's still pretty easy, but you'll need to download a package named "soul".
