I wanted to create a button, within the tiddler, that would allow me to edit the tiddler.
It might seem redundant since all tiddlers in the story view have such a button, but actually I am showing the tiddler as a header above the storyline ($:/tags/abovestory), and when it appears on top it lacks an edit button.
I thought of adding:
<$button>
<$action-sendmessage $message="tw-edit-tiddler" $param="Top"/>
edit
</$button>
