Thanks Charlie!
This code works:
<span style="font-size: 0.85em; font-weight: 600;">Schriftgröße (Editor):
</span>
<$range tiddler="fontsizeEditor" min="16" max="22" default="18"
increment="0.5" class="slider"/>
<span style="font-size: 0.7em"> {{fontsizeEditor}} px </span>
<$button class="tc-btn-invisible" tooltip="Reset">
<$action-setfield $tiddler="fontsizeEditor" text="18"/>
<span style="font-size:1em;">''↺''</span>
</$button>
