Insert mode is a mechanism that allows users to insert text without overwriting other text. This mode, if it's supported, is entered and exited by pressing the Insert key on a keyboard.
In Microsoft Word, this mode is called overtype mode.
Note
Not all programs support the ability to enable and disable the insert mode. For example, most browsers do not support the ability to disable insert mode with the Insert key.
Pressing a keyboard key delete letters
When insert mode is disabled, any key you press (e.g., spacebar) will overwrite the letter to the right of the text cursor. When insert mode is enabled, no text is overwritten and will be inserted before the text to the right of the cursor.
