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 NewBlogEntry macro.
Usage
Without parameters.
[[ShowMe()]]
Rendered as: show
With a single parameter indicating the hyperlink text.
[[ShowMe(the ShowMe macro page)]]
Rendered as: the ShowMe macro page

Discussion
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.
