Hello everyone! Today, I'd like to introduce a really useful feature when using your computer.
It's about a keyboard shortcut called 'Ctrl+Z'.
Using this function, you can easily fix mistakes when working on your computer.
What is Ctrl+Z?
Ctrl+Z is a special key on the computer that performs the 'Undo' function.
Just like erasing writing with an eraser, you can cancel what you just did on the computer.
How do you use it?
1. Find the 'Ctrl' key on your keyboard. It's usually at the bottom left of the keyboard.
2. Next, find the 'Z' key.
3. If you feel you've made a mistake, immediately press and hold the 'Ctrl' key, then press the 'Z' key once.
4. Ta-da! What you just did has been undone.
What's good about doing this?
1. You can easily erase when you've typed something wrong.
2. You can immediately recover a file if you accidentally deleted it.
3. You can easily fix mistakes when drawing a picture.
Ways to apply it
1. If you've made multiple mistakes, you can keep pressing Ctrl+Z to go back to previous steps.
2. When writing a document, if you deleted a sentence and then need it again, you can bring it back with Ctrl+Z.
3. When editing a photo, if you changed the color incorrectly, you can revert it to the original with Ctrl+Z.
Points to be careful about
1. It might be difficult to undo something you did a long time ago. Try to use it as soon as possible.
2. You can't use Ctrl+Z to undo things after turning the computer off and on again.
3. It might not work exactly the same in all programs.
4. Be careful as it might work a bit differently in internet browsers.
Good tips to know
1. There's also Ctrl+Y, which is the opposite of Ctrl+Z. If you've undone too much by mistake, you can go forward again with Ctrl+Y.
2. You can also use Ctrl+Z in File Explorer.
If you accidentally moved a file, you can put it back in its original place with Ctrl+Z.
3. In drawing programs, you can press Ctrl+Z multiple times to undo several steps.
It might feel a bit awkward at first. But with a little practice, you'll get used to it quickly!!
If you have any difficulties, it can be more fun to learn together by asking people around you!
