What is the function of the Ctrl + A keyboard shortcut?

• A. Deselect all
• B. Select all
• C. Copy all
• D. Paste all

Answer: (B)

The function of the Ctrl + A keyboard shortcut is to select all items in the current window or document. This means that when you use this shortcut, it highlights everything within the context you are working—whether that's text in a text editor, files in a file explorer, or objects in graphic software.

This keyboard shortcut is particularly useful for users who want to quickly manipulate their entire content, whether that be to copy it, format it, or delete it. Other options like deselecting all, copying all, or pasting all have different key combinations and functions. For instance, deselecting typically requires a different approach depending on the software, while copying is done using Ctrl + C, and pasting is executed using Ctrl + V. Therefore, understanding the specific functionality of Ctrl + A as a selection tool is crucial for efficient computer use.
