Ain't no action-delete for indices, so how?

In a dictionary tiddler, how can I delete a certain index (and its value)?

I was expecting the ActionDeleteFieldWidget to feature this, symmetrically to how ActionSetFieldWidget can set an index…?

<$action-setfield $tiddler=... $index="someindex" />

Note that there is NO $value=... parameter.

hahaaa! Excellent! Thanks Eric!

Your reply also made me fine comb for it in the docs and it turns out it is brought up in the ActionSetWidget where it, IMO, more intuitively should be in the ActionDelete tid. Luckily, the very thing I’m working on will hopefully soon contribute to correct such things.
