The keyboard shortcut "Command+X" is commonly used on Apple computers to cut selected text or items. When you press these keys together, the highlighted content is removed from its original location and stored in the clipboard, allowing you to paste it elsewhere. This function is particularly useful in applications like Microsoft Word or Pages, where you may want to reorganize text or images. After cutting, you can use "Command+V" to paste the content in a new location, making it a convenient tool for editing and managing information efficiently.
