* It is recommended that you add the custom buttons in an external
* file and leave this one unchanged . That ' s because when we
* ( InteractiveTools . com ) release a new official version , it ' s less
* likely that you will have problems upgrading HTMLArea .
*
* Example on how to add a custom button when you construct the HTMLArea :
*
* var editor = new HTMLArea ( "your_text_area_id" ) ;
* var cfg = editor . config ; // this is the default configuration
* cfg . btnList [ "my-hilite" ] =
* [ function ( editor ) { editor . surroundHTML ( '<span style="background:yellow">' , '</span>' ) ; } , // action
* "Highlight selection" , // tooltip
* "my_hilite.gif" , // image
* false // disabled in text mode
* ] ;
* cfg . toolbar . push ( [ "linebreak" , "my-hilite" ] ) ; // add the new button to the toolbar
*
* An alternate ( also more convenient and recommended ) way to
* accomplish this is to use the registerButton function below .
