I've found this code:

{let 
related=$node.object.data_map.keywords.content.related_objects}
{section show=$related}
<h2>Related documents</h2> 
<ol> 
{section name=Related loop=$related}
<li><a href={$:item.url_alias|ezurl}>{$:item.name}</a></li> 
{/section} 
</ol> 
{/section} 
{/let}

It's working fine...

...but I need something more, <b>limit this list to 5 items, from specified node and sorted by published date.</b>

How to develop this code? I couldn't find any solution at ez.no. I'm not a programmer and need your help.
I think it would be very usefull for many other beginners also.
sorry for my english :)

templates/content/datatype/view/ezkeyword.tpl from a recent project:

<p>{"Keywords used in this article:"|i18n("design/mydesign/keywords")}</p>
{def $keyword_array = $attribute.content.keyword_string|explode(',')
     $keyword_count = 0
     $keyword_string = ''}
{foreach $keyword_array as $keyword}
    {set $keyword_string = $keyword|trim()}
    {set $keyword_count = fetch( 'content', 'keyword_count', hash( 'alphabet', $keyword_string ) )}
    {if $keyword_count|gt( 1 )}
        <a href={concat('content/keyword/', $keyword_string)|ezurl}>{$keyword_string|wash}</a>
    {else}
        <span>{$keyword_string|wash}</span>
    {/if}
{/foreach}
{undef}

With this you can easily set limit using max parameter on foreach, and you can also add classid in url as parameter if you want to filter on that.

But look like you want to link directly to the articles that use same keyword, so you should probably look at:
