Press the " Control +C " key combination to copy the selected folder to the whiteboard. 5 Open a new text editor and paste the contents of the folder into the editor. 6 Find the table of contents that you just pasted on the whiteboard in the editor and press the "Control +V" key combination to convert the table of contents to plain text format. 7 copy the table of contents in plain text format into the document you want to convert so that you can rearrange and organize it when needed.
