How to Double-Click, Right-Click and Drag on a Mac

What you need: A Mac with a mouse or a trackpad, and a web page with words on it open on the screen, such as the practice page that opens when you click Start the demo below these steps on the website.

Steps

1. To double-click a word, put the pointer on a word in the middle of a line of plain words, not on a link (links are often blue or underlined). Keeping the pointer still, press the left mouse button twice quickly (on a mouse with a smooth top, press the left half of its top; on a trackpad, press down on it). The word is highlighted, shown with a colored background. If it is not, try again a little faster, without moving the pointer between the two presses. If a box with a dictionary entry opens instead, you pressed the trackpad harder: click an empty part of the page to close the box and press more lightly. If two quick presses are still hard, give yourself more time to double-click.
2. To right-click the highlighted word, keep the pointer on it. Hold down the Control key (marked control or ⌃, in the bottom row of the keyboard near the left corner; on many Mac keyboards it is the second key from the left), press the left mouse button or the trackpad once, then let go of both. A small menu of choices, such as Copy, opens beside the pointer. On a Mac this is called a Control-click or a secondary click.
3. To close the menu without choosing anything, click once on an empty part of the page, away from the menu and the words. The menu closes.
4. To highlight a whole line, put the pointer on a short line of plain words, such as a heading, and press the left mouse button or the trackpad three times quickly, keeping the pointer still. The whole line is highlighted.
5. To drag, put the pointer just in front of the first letter of a word. Hold down the left mouse button, move the pointer to the end of a word further along the line, and release the button. On a trackpad, press down until you feel a click and keep pressing while you slide your finger, then lift it. The words you moved across are highlighted.

Expected result: You highlighted one word by double-clicking, opened and closed a Control-click menu, highlighted a whole line by clicking three times, and highlighted several words by dragging across them.
