Hi all:
Jed: The button solution you suggested work fine (see listing below).
Erwan and Tobias: Thanks for your posts about (what I interpret to be) a
more generalized approach for addressing my use case.
Steve Wharton
```
<$button>Sort Tags
<$list filter='[!is[system]]'>
<$set name=TagsString filter='[<currentTiddler>tags[]sort[]]'>
<$action-setfield tags=<<TagsString>>/>
</$set>
</$list>
</$button>
<table>
<$list filter="[!is[system]tag[BC]sort[tags]]">
<$set name="sorted_tags" filter="[is[current]tags[]sort[]]">
<tr>
<td><$link to={{!!title}}><$view field="title"/></$link></td>
<td><$list filter="[all[current]tags[]sort[title]]"
template="$:/core/ui/TagTemplate" storyview="pop"/></td>
</tr>
</$set>
</$list>
</table>
```
