getting there.
<$edit-text tiddler="weight" index="tmp" tag="input" type="number"/>
<$button>
<$action-listops $tiddler="weight" $index="latest" $filter={{weight##tmp}}/>
<$action-listops $tiddler="weight" $index=<<now YYYY0MM0DD0hh0mm0ss>>
$filter={{weight##tmp}}/>record
</$button>
weight -> {{weight}}
weight##latest -> {{weight##latest}}
probably the key "latest" is not required. But needs a simple way to access
the latest value. I guess that it could be done with an filter but probably
harder compared to {{weight##latest}}
