= ShowMe macro =
It's no necessary because the Action macro accept a second parameter with free text. Usage: `[[Action(action, text)]]`. 

I'll keep `ShowMe` macro here for illustration.

== Description ==
Allow an inline link from a page to itself. Used to create custom links in included pages. Created to use with the [[macro/NewBlogEntry.py|NewBlogEntry]] macro.

== Usage ==
Without parameters.
{{{
[[ShowMe()]]
}}}
Rendered as: <<Action(show)>>

With a single parameter indicating the hyperlink text.
{{{
[[ShowMe(the ShowMe macro page)]]
}}}
Rendered as: <<Action(show, the ShowMe macro page)>> 

== Code ==
{{{#!python 
"""
    ShowMe

    Description
    ===========
    Create a link to the page where the macro appears. The parameter will be the hyperlinked text. If no parameter is passed then standard localization for 'show' action will be used.    
    @see http://moinmoin.wikiwikiweb.de/MacroMarket/ShowMe for more info.

    Usage
    =====
    [[ShowMe()]]
    [[ShowMe(free text)]]

It seems that this macro is not needed - see how the usage is created with `[[Action(action, text)]]` macro :-)
  * Thanks. I forgot trying this trivial parameter before start programming.
