Command Link
============

Purpose
-------

A *command link* is an area containing icon and text that is used to
initiate an action.

It is primarily designed to streamline Wizard-like interfaces and to
select from a set of mutually exclusive, related choices. Complementary
to command buttons, command links are used for navigation to other
places. Links behave similar to buttons but have always a clean,
lightweight appearance without stimulative nature.

Guidelines
----------

Is this the right control?
~~~~~~~~~~~~~~~~~~~~~~~~~~

-  Use command links for a set of mutually exclusive responses like
   navigation from hub to spoke pages.
-  Don't present single command links.
-  Consider to use a :doc:`push button <pushbutton>` for single commands 
   or if the action does not contain navigation.

Behavior
~~~~~~~~

-  Provide feedback when result is not aware to user or not available
   instantaneous. Display a busy pointer or present a progress bar to
   users.
-  Don't mix command links and command buttons at one place.

Appearance
~~~~~~~~~~

-  Command links are flat.
-  Use standard theme color for links.
-  Always apply an icon to command links.
-  Icons should have a size of 48x48 pixels.
-  Choose a concise, self-explanatory label that clearly communicates
   and differentiates what the command link does.
-  Don't use ellipsis.
