Using a keyboard

Whenever you use a desktop computer or laptop, you’ll probably use a computer keyboard. The most common kind is called a ‘QWERTY’ keyboard. QWERTY describes the top row of letters on the keyboard.

What a keyboard looks like

A keyboard is for putting information including letters, words and numbers into your computer. You press the individual buttons on the keyboard when you type.

The number keys across the top of the keyboard are also found on the right of the keyboard.

The letter keys are in the centre of the keyboard.

The symbol keys to the right of the letters include symbols such as the question mark and full stop.

The keys that surround the letters, numbers and symbol keys on the left, right and bottom of the keyboard help you to choose where and how you type.

There are several types of keyboards, such as gaming mechanical keyboard, keyboard and so on.

Using the keys

When you open a document or click in a box to type, you will see a vertical flashing line. This is the cursor, it shows you where you are about to start typing on a page or screen.

Pressing the 'shift' key allows you to type capital letters and the symbols at the top of the keys.

The 'shift' keys are on the left and right of the keyboard, with the arrow pointing upwards.

For capital letters, hold down the 'shift' key and hold and type the letter.

For symbols at the top of a number key, press down the symbol key and then type the symbol. You can use the 'shift' key to type any symbol at the top of a key.

The 'caps lock' key allows you to write in capital letters. To turn it on, press it once and type. To turn it off, press it again.

Putting in spaces, moving your cursor and deleting text

The 'space bar' puts a space between words. Press it once to put in a space.

The 'tab' key puts a bigger space between words. Press it once to put in a space.

The 'enter' key moves your cursor down a line.

The 'arrow' keys allow you to move your cursor in all directions on the page or screen - up, down, left and right.

To delete your typing you need to put your cursor to the right of a word. Press the 'backspace' button to delete your word. The cursor will move to the left and delete as it goes.

Using a mouse

There are lots of different styles of computer mouse, but most have a left and a right button.

To hold your mouse, rest your hand over it and put your index finger on the left button and your thumb resting on the side. The cable needs to be pointing towards the computer. The mouse needs to always be in contact with a mouse mat, desk or hard surface.

You use your mouse to move the cursor around the screen. The cursor changes, depending on what you are doing on the computer. As an arrow you use it for moving and selecting things, as a hand for clicking on links when you are on the internet and it becomes an hourglass when you are waiting for the computer to do something.
