What key must you press to select non-adjacent text?

To select non-adjacent text in a document, you need to use the Ctrl key in conjunction with your mouse or keyboard. By holding down the Ctrl key while clicking on different sections of text, you can highlight multiple segments that are not next to each other. This is particularly useful when you want to format or manipulate specific parts of your text without affecting the entire document.

In contrast, the Shift key is used for selecting adjacent text, where you click at the start of a section and then Shift-click at the end to select everything in between. The Alt key is typically used for accessing menus or commands rather than text selection, and the Enter key is primarily for inserting a line break or executing a command. Understanding how to use the Ctrl key for non-adjacent text selection is crucial for efficient document editing and management.
