====== Change CP anchor text ======

**RT: Give CP anchors meaningful names.**

This RT offers the possibility for CP anchors to give them "meaningful names".

An anchor that can be specified autom. for each CP e.g. **%%<a name="cpid123">%%** //(123 is the CP-Id)// \\
will become: **%%<a name="mein-toller-ankername">%%**   

These names are set in the respective CP 
  * With a TAG in the Notes field e.g. **[Xanchor:**nice-cp-text-anchor**]**
  * or titles or subtitles may be used for the text.

The settings have to be made in the script in CUSTOM VAR.

Additionally, you can set whether hidden CPs //(when working with CP alias or SHOW_CONTENT)// are involved in the process. //(Default: $visible_cp = false;)//

In front of each anchor a text can be defined, for example, **%%$prev_anchor = 'prev-';%%** === > **%%<a name="prev-nice-cp-text-anchor">%%**. \\
This is also adjusted in the script in CUSTOM VAR.

**Usable characters:**

(a-z A-Z) (0-9) (_) (-) (.) \\
All other characters are converted, for example  "Mein größter Ankertext" will be converted to "mein_groesster_ankertext". \\
All characters are converted to lowercase. If this isn't a wanted behaviour, please comment out the statement **%%$str = strtolower( $str );%%** in "%%function rt_val_special_chars($str)%%".

If you want another replacement this can be changed in the above Function.
