Chapter 1: Computer Basics / Lesson 2

Using a Mouse and Keyboard

Mastering the Mouse

The mouse is one of your primary tools for interacting with a computer. It controls a pointer (cursor) that you see moving on your screen. Understanding mouse basics is essential for using any computer effectively.

  • Moving the Mouse: Gently slide the mouse on a flat surface—the pointer on screen moves in the same direction. Don't lift the mouse while moving unless you run out of space (then lift and reposition)
  • Left-Click: Press the left button once to select items, open menus, or activate buttons. This is the most common action
  • Right-Click: Press the right button to open a context menu with options related to what you clicked on
  • Double-Click: Quickly press the left button twice to open files or programs
  • Click and Drag: Hold down the left button, move the mouse, then release to move items or select text
  • Scroll Wheel: Roll the wheel up or down to scroll through long pages or documents

Mouse Practice Exercise

Try these exercises to improve your mouse skills:

  1. Move the mouse slowly and watch the pointer move on screen
  2. Move the pointer to different icons on your desktop without clicking
  3. Practice single-clicking on different items
  4. Try right-clicking to see context menus appear
  5. Practice double-clicking to open programs

Understanding the Keyboard

The keyboard allows you to type text, numbers, and commands into your computer. Learning keyboard layout and special keys will make you more efficient.

  • Letter Keys: The main typing area with all 26 letters arranged in QWERTY layout (named after the first 6 letters on the top row)
  • Number Keys: Numbers 0-9 at the top row, plus a separate number pad on the right (on most desktop keyboards)
  • Shift Key: Hold down and press a letter to make it CAPITAL, or press number keys for symbols (!, @, #, $, etc.)
  • Enter/Return: Creates a new line in documents or confirms actions in forms
  • Spacebar: The long horizontal bar creates spaces between words when typing
  • Backspace: Deletes text to the left of the cursor (the blinking line showing where you're typing)
  • Delete: Removes text to the right of the cursor or deletes selected items
  • Tab: Moves the cursor forward by several spaces or jumps between fields in forms
  • Arrow Keys: Four keys (up, down, left, right) that move the cursor or selection

Typing Fundamentals

Learning to type efficiently takes practice. Here are the fundamentals:

  • Home Row Position: Rest your fingers on ASDF (left hand) and JKL; (right hand) when not typing. These are your "home" positions
  • Finger Placement: Each finger is responsible for specific keys—this allows for faster, more accurate typing
  • Proper Posture: Sit up straight, keep your wrists straight, and position the keyboard at a comfortable height to prevent strain
  • Look at Screen: Don't look at your keyboard while typing—watch the screen to see what you're typing
  • Practice Regularly: Start slowly, focusing on accuracy rather than speed. Speed will come with practice

💡 Typing Tips for Beginners

Use all ten fingers, not just your index fingers. Take breaks if your hands get tired. Practice daily for just 10-15 minutes. Use online typing tutorials and games for practice. Remember: accuracy first, speed second!

Keyboard Shortcuts

Keyboard shortcuts are combinations of keys that perform actions quickly. Learning these saves time:

  • Copy (Ctrl+C / Cmd+C): Copies selected text or items to clipboard
  • Paste (Ctrl+V / Cmd+V): Pastes copied content at cursor location
  • Cut (Ctrl+X / Cmd+X): Removes selected content and copies it to clipboard
  • Undo (Ctrl+Z / Cmd+Z): Reverses your last action—very helpful if you make a mistake!
  • Save (Ctrl+S / Cmd+S): Saves your current work—use this frequently!
  • Select All (Ctrl+A / Cmd+A): Selects everything in a document or on a page
  • Find (Ctrl+F / Cmd+F): Opens search box to find specific text
  • Print (Ctrl+P / Cmd+P): Opens print dialog

Note: Windows vs Mac

On Windows computers, shortcuts use the Ctrl key. On Mac computers, use Cmd (Command) key instead. The functions are the same, just different modifier keys!

Combining Mouse and Keyboard

Most computer tasks require using both the mouse and keyboard together:

  • Click and Type: Click in a text field (like a search box) with the mouse, then type using the keyboard
  • Select Text: Click and drag over text to select it, or double-click a word to select the whole word
  • Copy and Paste: Select text with mouse, press Ctrl+C to copy, click where you want it, press Ctrl+V to paste
  • Multi-Select: Hold Ctrl (Cmd on Mac) while clicking to select multiple items
  • Right-Click Menus: Right-click items to see options, then use keyboard arrows to navigate menus if needed

💡 Practice Makes Perfect

Don't worry if using the mouse and keyboard feels awkward at first. Like any skill, it takes practice. Start with simple tasks and gradually work up to more complex actions. Within a few weeks of regular use, these actions will become second nature!
