Oh! for anyone who really needs to do on the spot presentation to a small crowd using your own laptop, quick tip if you got a multitouch screen. (e.g. surface pro)
You can use your fingers to zoom and scroll to a location on the page.

Observation about getting this to work. I was not able to find preference easily as a beginner, as I didn't realise that you need to right click the screen.
The preference menu needs to be accessible from the menu bar. Also it would be handy if there is a "quick preference" section in the menu bar where you can quickly toggle most used settings like math delims.
