Those of you using relatively recent Mac laptops can use the two finger trackpad scroll. As its name suggests, if you put two fingers on the trackpad you can scroll, much like a scroll wheel on a mouse. A very handy and labour-saving tool!
You can customise the way your trackpad works by going through the Keyboard & Mouse system preference and selecting the Trackpad tab. There you will find options to select two finger scrolling, plus you can opt for a zoom function using two finger scrolling in conjunction with a key (“ctrl” by default, but you can change this).
There are options that also allow you to use the trackpad to click, drag and drag-lock objects; it all depends how you like to work.
