Sometimes displayed as Ins, the Insert key is a located on most computer keyboards by the backspace key. The Insert key toggles how text is inserted by either inserting the text in front of other text or overwriting text to the right of the cursor as you type.
Example of using the Insert key
For example, in a word processor, if the I-cursor is placed in front of any text, nothing is overwritten as you type. However, if the Insert key is pressed and the I-cursor changes to a block cursor or enters overtype mode, as you type the text is overwritten.
In the example animated picture, you can see each mode in action. In the Overtype Mode when "test" is being typed it overwrites "Computer" to become "test ter" with the text being overwritten.
Note: Not all programs allow you to change the insert method with the Insert key. If the cursor does not change when you press the Insert key, text input mode toggling it is not supported.

In the additional example image, you can see the different cursors (I-beam cursor on the top and block cursor on the bottom). In the top portion, if we were to type "test " in front of "Computer Hope example" it would become "test Computer Hope example." However, if we pressed the Insert key to change the insert method, the result would be different. Typing "test" in this instance (bottom portion of the image) would make the text "test ter Hope example" because the first part of the text would be overwritten.
