If you choose Title while editing a simple field, the cursor moves to the first character of the title. Type the new title over the existing text in the window.

By default, you are in overstrike mode so that the characters you type replace the characters at the cursor position. To insert characters without overstriking, press the key defined as the Mode key on your keyboard to change to insert mode.

When in insert mode, move the cursor with an arrow key to where you want to insert characters, and type the insertions. Increasing the width of a component shifts existing components to the right.
