Basic Copy and Paste

Mastering the art of copying and pasting is essential for efficient workflow. Here are the fundamental shortcuts for these actions:

Action	Windows/Linux/ChromeOS	Mac
Copy	Ctrl + C	Cmd + C
Cut	Ctrl + X	Cmd + X
Paste	Ctrl + V	Cmd + V

To select text using your keyboard:

1. Use the arrow keys to navigate to the desired starting point.
2. Hold down the Shift key.
3. Use the arrow keys to highlight the desired text.

Once the text is selected, press the appropriate copy or cut shortcut. Navigate to the location where you want to paste the content and press the paste shortcut.

For Windows users, pressing Windows + V opens the Clipboard, allowing you to paste previously copied items.

Undo and Redo Commands

Accidentally deleted an important paragraph or made an unintended change? Don't worry! Undo and Redo commands are here to save the day. These essential shortcuts allow you to quickly reverse or restore actions, saving you time and frustration.

Action	Windows/Linux	Mac
Undo	Ctrl + Z	Cmd + Z
Redo	Ctrl + Y or Ctrl + Shift + Z	Cmd + Shift + Z

Here's how these commands work:

1. Undo (Ctrl + Z or Cmd + Z): This shortcut reverses the last action or change made to a document, allowing you to revert the file to its previous state. You can use this command multiple times to undo a series of actions.
2. Redo (Ctrl + Y, Ctrl + Shift + Z, or Cmd + Shift + Z): This shortcut reverses the last Undo action, restoring the file to a more recent state. The Redo command can only be used after an Undo command has been executed.

In many applications, such as Microsoft Office, you can find visual indicators for these functions under the "Home" tab. Look for a left-facing arrow for Undo and a right-facing arrow for Redo.
