Mission Contol solves the "too many window" problem A number of pages one can open on a computer screen--for example while browsing, or while writing a book (where each section might be in a different doc file)--can be very large. But working on a desktop overpopulated with windows is likely to be very inconvenient, especially when the screen is small. The application named Mission Control, that comes with Lion, the latest Macintosh operating system, offers two tools for dealing with "too many windows" situations. After learning how to use Mission Control, I decided to summarize what I have learned, in a short introductory User's Guide. How can a retired teacher miss an opportunity to teach? The guide is freely available online at http://pages.csam.montclair.edu/~kowalski/lion_mc.html Feel free to use it in any way you wish. And share what you know about Mission Control. Thank you in advance. .
