Color the keyboard keys using the provided color guide for educational purposes.

To solve this worksheet, you need to look at a standard computer keyboard and match each key listed in the instructions to its color. Since I cannot physically color the image for you, I will list exactly which keys correspond to each color so you can color them in yourself.

Here is the step-by-step breakdown based on the guide provided:

1. BLUE Keys (Number keys)
These are the keys with numbers on them, located in the top row of letters.
* Color these keys Blue: `1`, `2`, `3`, `4`, `5`, `6`, `7`, `8`, `9`, `0`

2. GREEN Key (Tab key)
This key is usually on the far left side, above the Caps Lock key.
* Color this key Green: `Tab`

3. YELLOW Key (Shift key)
There are two Shift keys on most keyboards (one on the left and one on the right). The instructions say "Shift key," so you should color both if they are present, or just the main left one if following strictly. Usually, worksheets imply both.
* Color these keys Yellow: `Shift` (Left) and `Shift` (Right)

4. PURPLE Key (Backspace key)
This key is typically in the top right area of the main letter block. It might have an arrow pointing left ($\leftarrow$) or say "Backspace."
* Color this key Purple: `Backspace`

5. RED Key (Spacebar key)
This is the long, empty bar at the very bottom center of the keyboard.
* Color this key Red: `Spacebar`

6. BROWN Key (Caps lock key)
This key is on the far left side, below the Tab key.
* Color this key Brown: `Caps Lock`

7. PINK Key (Enter key)
This key is on the right side of the keyboard. It is often shaped like an upside-down "L" or a large rectangle. It might say "Enter" or have a bent arrow ($\hookleftarrow$).
* Color this key Pink: `Enter`

8. ORANGE Key (alt key)
There are usually two Alt keys, located on the bottom row next to the Spacebar.
* Color these keys Orange: `Alt` (Left) and `Alt` (Right)

9. GRAY Key (ctrl key)
There are usually two Ctrl keys, located on the far bottom corners of the keyboard.
* Color these keys Gray: `Ctrl` (Left) and `Ctrl` (Right)
