For me it was something like:
Search for On Save (nothing useful or rather too many items, Subscribe is there if you scroll down to Prototype matches but I didn't and most likely I wouldn't have even tried it)
Try On Close to see which could be correct category (too many categories to really filter that down quickly)
Notice Subscribe to Data Table List (I'm familiar with that one so I went with that, Subscribe was visible here). Click on that and it selects Row from left (no idea why it is Row and not Data Table)
Remove search term to get only Row related items and check if that would have something useful (found nothing useful).
Update my search term to Subscribe to find more things related to that and notice that there is Subscribe message (for Data Table) and it happens to support On Save
There were few steps where I could have noticed Subscribe earlier but I didn't (this time). Most likely easiest way to find it could have been something like "Search for "On Save", select Data Table from left to find only Data Table related items and hope for best"
