[ln wikipedia]topic[/ln]
[ln php]htmlentities[/ln]
[ln amazon]978-0321396853[text]Eclipse Web Tools Platform[/text][/ln]
Or you can add links by clicking the ‘ln’ button inside of the wysiwyg editor. This will bring up a dialog box where you enter in the necessary data for that particular link

<ul>

Adds explaining tooltips querying their content from a <a href="https://www.mediawiki.org" title="see MediaWiki docs" rel="nofollow ugc">MediaWiki</a> installation, e.g. <a href="https://www.wikipedia.org" title="see the well-known Wikipedia" rel="nofollow ugc">Wikipedia.org</a>. Therefore shortcodes can be used in Posts and Pages to mark keywords and link them to public Wiki pages. The well-known package of <a href="https://calebjacob.github.io/tooltipster/" title="Tooltipster rocks :)" rel="nofollow ugc">Tooltipster</a> is used to create the nice and themable tooltips.
Main features of the current version are:
<ul>
<li>Setup at least one wanted Wiki base and several other options at a backend page</li>
<li>Integrate the Wiki tooltip in Posts and Pages using a handy popup in Gutenberg editor or simple shortcodes</li>
<li>Shortcodes can be created by a <a href="https://codex.wordpress.org/TinyMCE" rel="nofollow ugc">TinyMCE</a> plugin, too</li>
</ul>
