Thanks a lot, @vitor — can't believe you were able to pick that up so quick and update
The ⇧↩ enabled on the Fallback Search is amazing and works exactly as I'd hoped!
A follow up question on the ⇧↩ action when using gd — it appears to work only for when there's a match in the results populated via Script_filter_items. Would it be possible add a result at the end of that array that when actioned, conducts the search online? For example, if I have multiple documents in Google Drive with the word 'test' in title, it pops up the following results:
However, when searching for test online, there are results that include 'test' in the document itself, or perhaps in titles of documents shared with me, etc.
Therefore, by having an option accessible at the end of the search results shown, or via ⌘4 in this instance, I can quickly pop up that full view in the browser. I could of course get around this by just searching in the default Alfred bar, but my brain is trained pretty heavy on my shortcut to access the Google Drive workflow when looking for a particular document (and in the case that it's not in my drive folder, or the gd filter returns no results, I could then quickly conduct a full search online).
Additionally, actioning the "Nothing Found" item in the results window with ⇧↩ doesn't appear to do anything either.
