Batch change ´Include in Draft"

This possible? For example on the items of a search result? If not, consider this a feature request…

Opt-click in the outliner view. Or “Include/exclude all” in Compile Draft.

Sorry, but I do not get this. When I have a selection of multiple items in the search results, option-clicking will deselect the group and select just one. Also, when I have multiple item selected in search results or corkboard view, for example, changes will only affect one item. Could you hold my hand through this one?

Sorry, you can’t do it in the search results pane. When I said “outliner”, I meant the outliner view itself (the alternative view to the corkboard that opens in the main editor) - if you have the “Include in…” column visible, you can opt-click on it.
Best,
Keith
