Hello everyone! Today, I'd like to introduce a really useful feature when using your computer.
It's about a keyboard shortcut called 'Ctrl+O'.
Using this function, you can open the files you want very easily.

What is Ctrl+O?
Ctrl+O is a special key combination on the computer that performs the 'Open File' function.
Just like opening a drawer to take out what you want, you can easily open files stored on your 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 'O' key.
3. Press and hold the 'Ctrl' key, then press the 'O' key once.
4. Ta-da! A window appears where you can select files.
What's good about doing this?
1. You can quickly find and open the files you want.
2. You use the mouse less, so your wrist doesn't hurt as much.
3. It makes using the computer faster and easier.
Ways to apply it
1. When working on documents: You can quickly open previously written documents.
2. Viewing photos: You can easily find and view old photos.
3. On the internet: You can quickly open and attach saved files.
Points to be careful about
1. It might work slightly differently in different programs.
2. Be careful as your current work might disappear when opening a file.
3. Opening too many files at once can slow down your computer.

Good tips to know
1. Pressing Ctrl+S will save the file you're currently working on.
2. Pressing Ctrl+N will create a new document.
3. For frequently used files, creating shortcuts on the desktop can make them easier to find.
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!
Computers are tools that make our lives more convenient.
As you learn these small tips one by one, you too can become a computer expert. Fighting!
