How do you switch from insert mode to overtype mode?

To switch from insert mode to overtype mode in most text editors, you can typically press the "Insert" key on your keyboard. This toggles between the two modes, with insert mode allowing you to add text without overwriting existing characters, and overtype mode replacing existing characters as you type. If your keyboard doesn’t have an "Insert" key, you may need to use a specific keyboard shortcut or check the settings of your text editor for an option to change modes.
