Using a computer

Computer skills

The quiet superpowers: keyboard shortcuts, finding your files, the right-click menu, and what that scary black "terminal" actually is. Learn these and you will fly.

1. Keyboard shortcuts

A shortcut does in one keypress what takes several clicks. The big ones, used everywhere:

ShortcutWhat it does
Ctrl+CCopy
Ctrl+VPaste
Ctrl+XCut
Ctrl+ZUndo
Ctrl+ASelect all
Ctrl+SSave
Ctrl+FFind on the page
Alt+TabSwitch between open windows
Alt+F4Close the current window
WinOpen the Start menu (then just type to search)
On a Mac? Swap Ctrl for Cmd (⌘): Cmd+C, Cmd+V, Cmd+Z, and so on.

Check your understanding: You made a mistake and want to undo it. Which shortcut?

2. Shortcut trainer

Real practice beats reading. Press Start, then actually press the keys for each action. (We catch the keypress, so Save and Find will not pop up.)

Press Start to begin.

 

Alt+Tab, Alt+F4 and the Win key are controlled by the operating system, so a web page cannot catch them. Try those for real on your own computer!

3. Files, folders & right-click

File Explorer (the yellow folder on the taskbar) is where all your stuff lives. Things are kept in folders, which can hold more folders, like boxes inside boxes. The trail to a file is its path, for example Documents\Year 7\essay.docx.

The end of a file name is its extension, and it tells you the type: .txt plain text, .docx a Word document, .png/.jpg an image, .mp4 a video, .py Python code.

The right-click (or two-finger tap on a laptop) opens a menu of things you can do right here: New → Folder, rename, delete. Here is a mini File Explorer to play in: double-click a folder to go inside (watch the path at the top), single-click to select it, and right-click for the menu.

Check your understanding: A file is called holiday.png. What kind of file is it?

4. What is a terminal?

The terminal (also called the command line, Command Prompt, or PowerShell on Windows) looks scary, but it is simple: instead of clicking to do things, you type commands. It is just another way to talk to the computer, and it is how programmers do a lot of their work.

# list what is in this folder
dir

# go into a folder
cd Documents

You will not break anything by looking. Many powerful tools only have a terminal, so it is worth not being scared of it.

5. Handy tips

  • Snap windows: drag a window to the left or right edge (or press Win+/) to fit two side by side.
  • Search anything: tap the Win key and just start typing the app or file you want.
  • Screenshot: Win+Shift+S lets you snip part of the screen.
  • Find on a page: Ctrl+F jumps to any word on a website or document.
  • Re-open a closed tab: Ctrl+Shift+T in a browser.
