You can add the tagged value "autofocus" and set it to true on an input field to ensure it is automatically selected when it appears in a view.

Update the Designer from the Wiki and get this tagged value template into your Designer.

For example, do this:

<a href="/File:Autofocus_example.gif" class="image" data-bs-title="File:Autofocus_example.gif" data-bs-filetimestamp="20210624200445"><img alt="Autofocus example.gif" src="/images/d/dc/Autofocus_example.gif" decoding="async" width="768" height="320" class="thumbimage" /></a>

<a href="/File:Autofocus_example.gif" class="internal" title="Enlarge"></a>
