-To create new text files, use `txt new "<My title>"` where <my title> is the initial title you wish the text to have. It's important to enclose the title with quotation marks if it contains spaces. The command will return the filename of the new text. The filename starts with a part of the ID and the title of the text. Use the file name to open it with your text editor.
