How can the standard-features word-processing programs be exploited for teaching writing skills?

Word processing programs allow people to produce typed documents on a computer screen. Although the lines between word processing and desktop publishing have become increasingly blurred, the programs still differ in the way they produce documents. Word processing programs essentially produce documents as a stream of text, whereas desktop publishing produces them as individual pages. Despite this difference, most word processing programs allow at least some desktop publishing capabilities, such as inserting text boxes and graphics at any location on the page. 

Some of the features we can use are:

Basic features help us to save time writing text and make changing text easier and more flexible.

Language features help teachers and students to correct their work and do various languages, spelling, and usage exercises, check and correct spelling, suggest words, check grammar and usage.
Web features allow teachers and students to connect documents with Internet resources and create web page announcements, reports, and projects.

On the other hand, when students do receive instruction in typing and text editing, it is not surprising that they become skilled at these tasks because they are in contact with them and the instructions give them a guide for using them in the appropiate way.
