CMD + D is a keyboard shortcut to enable sublime-like multiple cursors in any text field on the web.

How to enable multiple cursors

In any text field on the web (i.e., a textarea), you can enable multiple cursors with CMD + D. Multiple cursors are a very useful feature that makes editing very easy. You can select, copy, or move text from one place to another with one finger. It's especially useful for those with a limited amount of free hand movement.

The CMD + D shortcut will let you select more than just one word at a time. For example, you can select an entire sentence, press CMD + D, and then press DELETE to remove it all from the text field. If you want to highlight all the words that start with a certain letter, you can do so with the CMD + D shortcut.

How to use multiple cursors with one finger

When you press the CMD + D keyboard shortcut, you'll see the first word that you select highlighted. Now just hold the SHIFT key and press the word to select the next one.

Now you can select multiple words at the same time. You can use one finger to move from one to another.
