The bottom of the touchpad has a click function, like you click a mouse. You have the usual right-click and left click function. You just click and hold down while dragging your finger across the main portion of the pad to highlight text, etc. It functions just like a mouse, you’re not losing anything. You can buy a USB mouse if you want, but it’s not necessary.
Ah, ok, that’s what my wife was seeing.
I do use a small mouse when I have room, esp. for more intense work, but it’s not particularly practical in the car (that assumes I’m NOT driving!) and similar situations.
Thanks!
