End Key is used to move the cursor to the end of the line.

Explanation:
The End key is a keyboard key that is used to move the cursor to the end of the current line. It is especially useful when you are editing or typing a document and need to quickly navigate to the end of a line without using the arrow keys or the mouse.

Benefits of using the End key:
1. Saves time: Instead of manually moving the cursor to the end of the line using the arrow keys or mouse, the End key allows you to quickly jump to the end of the line with a single key press.
2. Convenient editing: When editing a document or code, you often need to make changes at the end of a line. Using the End key makes it easier to position the cursor precisely where you want it.
3. Efficient navigation: If you want to quickly read or review the contents at the end of a line, the End key allows you to instantly move to the end without scrolling or dragging the cursor.

Using the End key:
To use the End key, follow these steps:
1. Position the cursor anywhere within a line of text.
2. Press the End key on your keyboard.

The cursor will immediately move to the end of the line, allowing you to begin typing or editing at that point.

Alternative methods:
If your keyboard does not have an End key, you can also achieve the same result using alternative methods:
1. Use the combination of the Fn key (if available) and a function key that has an End symbol printed on it.
2. Use the Ctrl key along with the right arrow key to move the cursor to the end of the current word. Repeat this action until you reach the end of the line.
3. Use the combination of the Ctrl key and the End key on the numeric keypad (if available).

Conclusion:
The End key is a useful tool for quickly moving the cursor to the end of a line, providing convenience and efficiency when editing or navigating through a document or text.
