If your laptop has a synaptics touchpad, which is a quite commen build-in touchpad. There is a driver which supports pinch to zoom. This works well on my Lenovo T500 Laptop. On my macbook air with windows on bootcamp the touchpad driver already supports multi touch gestures.
Both support zoom in SH5 nav map.
But even so it is working I still use a USB Mouse whenever I have a place to use it.
