Writing on a computer is the most efficient, time saving method of reorganizing and improving the content of your paper. You can add, change, and delete words, phrases, sentences, or whole paragraphs with just a few keystrokes. You can also move items from one location to another in a flash, and if you don't like the change you just made, you can change it back instanly.
Another advantage of using a computer is that you can tell the computer to proofread your paper for spelling errors. Most word processing programs have spelling checkers built into them. Most also automatically correct errors in capitalization. However, you must still proofread your paper yourself because a computer may not find all of your errors.
As your word processing skills improve, you can start adding boldface and hand type or even photos, charts, and graphic design in your papers, the possibilities are almost unlimited, it is well weath your time and effort to learn to use a computer for writing.
