Add Tooltip to Inline citation

[someonehere15]

So making a separate post.
Can you add a tooltip to the inline citation, so it shows the reference when hovering mouse, without the need to click it to jump to the end?
Or you can help me to do it myself.
Thanks

Any tip how to do this myself?

You have to first use a library to display tooltips (maybe there is one in WordPress), and then modify the javascript code (papercite.js) so that it displays the entries when the mouse is over the citation. For this, you need to modify line 681 of papercite.php so that it wraps the citation into a <span> with a given class, so it can be detected by the javascript, e.g.

$returns .= "<span class='papercite-bibcite-key' value='$num'>$id</span>";
