One is the overwrite mode, the newly input word at the cursor position will replace the original word; the other is the insertion mode, the newly input word is inserted into the cursor position, and the original word is moved back accordingly. In early computer terminals, if in overlay mode, the cursor would become a square instead of the usual vertical line.
Function:
A flashing cursor will appear after clicking the input box with the mouse. Under normal circumstances, the Windows system inserts characters at the default cursor position, and the cursor moves backward, that is, the characters behind the cursor are not affected during input. However, Insert is embedded, that is, inserted and overwritten, so when the Insert key is pressed and then entered, the character behind the cursor will be erased, that is, replaced by the currently input character. After pressing again, it will return to the default insertion state.
