When you're using a computer, you "click" links, buttons, and icons to make things happen. This means that you move your cursor over an item using your mouse or track pad, and then you press a button on the mouse or track pad to make something happen.
Click where it says "Troubleshooting".
When you just need to click something once to make something happen, it's called "clicking" the item. Sometimes you need to click something twice to make it work. This is called "double clicking".
Double click the orange and blue icon on your desktop.
On a smart phone or tablet computer, we don't use the word "click". We use the word "tap" instead:
A: Tap the green button.
B: I already tapped it!
