The rule applies to screens, keystrokes, mouse clicks, menu options, pretty much anything.

In general, I mean that more is not better regardless of what most people think. A user wants the fewest number of screens than it takes to complete a logical task (this is the users logic, by the way). Assuming that a user is already accomplishing a task using a tool, then ask any user if they want a particular feature added to that tool and they will almost always say yes. Ask any user if they will use a particular feature and they will almost always say yes. Come back six months later and see if they are using that feature, they almost always will not be unless the feature significantly cuts down on the number of screens they access, or the number of keystrokes or mouse clicks etc. (well, one might be but there is usually one odd ball in the lot).

That's why it is a 10:2 rule to give a sense of proportion. (not absolute)

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
