Mouse Techniques – JSS1 Computer Studies Lesson Note (Third Term)

A mouse is a small device that helps us control the computer. When we move the mouse on a flat surface, a pointer (also called a cursor) moves on the screen. The mouse lets us select things, open programs, and do many tasks on the computer without using the keyboard.

Behavioural objectives

By the end of the lesson, students should be able to:

1. Name the main parts of a mouse and state what each part does.
2. Hold a mouse correctly.
3. Point, click, double-click, right-click, drag and scroll with a mouse.
4. Select single and multiple items using the mouse and the Shift and Ctrl keys.
5. Solve simple mouse problems and take care of a mouse.

What are the parts of a mouse?

• Body: The main part that fits in your hand.
• Left button: The main button used for most clicks.
• Right button: Used for special menus and options.
• Scroll wheel: The wheel between the buttons that helps move up and down on pages.
• Sensor: Located on the bottom, it tracks the mouse movement.

How do you hold a mouse?

Holding your mouse correctly helps prevent hand pain.

• Place the mouse on a flat surface like a desk or mouse pad.
• Rest your hand gently over the mouse.
• Place your index finger on the left button.
• Place your middle finger on the right button.
• Rest your palm on the back of the mouse.
• Keep your wrist straight, not bent up or down.
• Move the mouse using your whole arm, not just your wrist.

What are the basic mouse actions?

Pointing

• Move the mouse to place the pointer on an item.
• The pointer usually looks like an arrow.
• When it is over text, it often changes to an I-beam shape.
• When the computer is busy, it may show as an hourglass or spinning circle.

Clicking

• Single click: Press and release the left mouse button once.
• Use for: selecting an item, placing your cursor in text, pressing buttons.

Double-clicking

• Press and release the left mouse button twice quickly.
• Use for: opening programs or files, selecting a word in text.

Right-clicking

• Press and release the right mouse button once.
• Use for: opening special menus with more options.
• These menus are called “context menus” because they change depending on what you click.

Dragging

1. Place the pointer on an item.
2. Press and hold the left mouse button.
3. Move the mouse while holding the button.
4. Release the button when done.

Use for: moving files or folders, selecting multiple items, drawing.

Scrolling

• Turn the scroll wheel backward (toward you) to move down a page.
• Turn the scroll wheel forward (away from you) to move up a page.
• Some mice allow sideways scrolling by tilting the wheel left or right.

What are the advanced mouse techniques?

Hover

• Place the mouse pointer over an item without clicking.
• Use for: seeing tooltips, previewing links, activating certain buttons.

Triple-click

• Click the left button three times quickly.
• Use for: selecting a paragraph in many text programs.

Drag and drop

1. Drag an item as described above.
2. Move it to a new location.
3. Release the mouse button to “drop” it there.

Use for: moving files between folders, rearranging items.

Selection techniques

Select a single item: Click once on the item.

Select multiple items that are next to each other:

1. Click the first item.
2. Hold down the Shift key.
3. Click the last item.
4. All items between will be selected.

Select multiple items that are not next to each other:

1. Click the first item.
2. Hold down the Ctrl key (Command on Mac).
3. Click each additional item while holding the key.

Select with drag:

1. Click in an empty area.
2. Drag to create a selection box.
3. Release to select everything inside the box.

What special things can the scroll wheel do?

• Zoom: In many programs, hold Ctrl (Command on Mac) and scroll to zoom in or out.
• Middle-click: Pressing the scroll wheel like a button can:
  • open links in new tabs in web browsers
  • show special scroll mode in some programs
  • close tabs in some programs

How is the mouse used in different programs?

Web browsers

• Back/Forward: Some mice have side buttons for this.
• Open in new tab: Middle-click on a link.
• Close tab: Middle-click on a tab.
• Zoom: Ctrl+scroll (Command+scroll on Mac).

Photo and document viewers

• Zoom: Ctrl+scroll.
• Pan: Click and drag when zoomed in.
• Rotate: Alt+drag in some programs.

Text editing

• Select text: Click and drag across text.
• Select a word: Double-click on the word.
• Select a paragraph: Triple-click in the paragraph.
• Copy selected text: After selecting, right-click and choose Copy.
• Paste text: Right-click where you want the text and choose Paste.

How do you fix common mouse problems?

If your pointer moves in jumps or stops moving

1. Clean the bottom of the mouse.
2. Try using a mouse pad.
3. Check for low batteries if using a wireless mouse.
4. Make sure the surface is not reflective or transparent.

If clicking does not work properly

1. Check if the mouse is connected properly.
2. Restart the computer.
3. Check mouse settings in the control panel.
4. Try another mouse to see if the problem is with the mouse or the computer.

Which mouse settings can you change?

Most computers let you change how your mouse works.

• Pointer speed: How fast the pointer moves when you move the mouse.
• Double-click speed: How quickly you need to click twice for a double-click.
• Button configuration: Switch the left and right buttons if needed.
• Pointer appearance: Change how the pointer looks.
• Scroll speed: How fast pages scroll when you use the wheel.

What mouse tips help users with special needs?

• Larger mouse: Helps people with hand control difficulties.
• Trackball: A good alternative if moving a mouse is hard.
• Pointer trails: Make the pointer easier to see.
• Slow down pointer: Helps with precision if you have tremors.
• Magnifier: Many systems have tools to enlarge part of the screen.

How do you take care of a mouse?

• Clean your mouse regularly with a soft cloth.
• Keep food and drinks away from your mouse.
• Do not drop your mouse or pull on the cord.
• Replace batteries in wireless mice when needed.
• Store wireless mice safely when not in use.
