As a result, they have faced many difficulties and have always wanted a replacement for the insert key on their Mac keyboard. However, people who have bought Macintosh keyboards have complained of not having an insert key on Mac. For example, Shift+Insert is used as another method to paste text into a document. Not only does the key help in correcting errors but it is also used as a shortcut key along with other keys for various functions. The Insert Key is used to toggle how text is inserted by either inserting the text in front of the other text or overwriting the text to the right of the cursor as we type.
Also, it is present in the numeric keypad with 0 and works when the num lock key is turned off. The Ins or Insert Key is located near to Backspace key in most computer keyboards.
