Print text in the color that tells the user to take an action.

    This command prints text in the color that tells the user to do
    something.  By using a consistent color as a call to action, and using
    that color only when a user action is needed, we get the user in the
    habit of knowing they need to do something when they see the color.

    For predictable results, use quotes around the text to print.

Examples:

    # The message will appear in the color for actions.
    > action "Cycle your session to pick up the changes."
    Cycle your session to pick up the changes.

Usage: action <action:*> # Where action is:

    help  Help by showing these instructions.
    *     Print the message given in the first parameter.  [default]
