The main area of the composing space is the text editor. You use the editor much as you would a word processor. Type the document directly in the editor or paste text copied from another application, such as Microsoft® Office Word. Use the icons across the top of the editor to perform standard word-processing tasks—such as Find, Copy, Paste, Paste from Word, Fullscreen Mode, Undo, and Redo—and to format text and insert links.
You may also find it useful to increase the size of the editor.
The composing space automatically saves your work after a set period of time, but save your work frequently just as you would in any word processor. Especially save an open document before walking away from the computer, texting, checking tweets, etc.—it is so easy for a distraction that might take just a minute to take an hour. When you return, save the document again.
