• https://docs-staging.datadoghq.com/janine.chan/docs-9287-cmd-k-search/getting_started/application/:
  the copy says "...pages, entities, and common actions..." can we remove the "actions" part? cuz I think we actually have an entity called actions, and you cannot get those in cmdK right now. i'd also like to give an example of an entity in the copy too, so maybe saying "Tip: You can press Cmd/Ctrl + K to search for pages and entities like dashboards & monitors across Datadog."?

• https://docs-staging.datadoghq.com/janine.chan/docs-9287-cmd-k-search/metrics/
  I'm worried that saying "to open your metrics from DD's global search, press..." will make people think they can search for distinct metrics within cmdK, which you also cannot do. Maybe say "to view a list of all your metrics from DD's gsearch.." or "to open the Metrics Summary page from DD's gsearch..." would be clearer?

• https://docs-staging.datadoghq.com/janine.chan/docs-9287-cmd-k-search/service_management/events/
  so right now, if you type "Events" in cmdK, the top result will open not a list of individual events, but rather GROUPS of similar events (aka the Correlated Events view, which is new and not well adopted). if users want to see a list of distinct events, they need to type "Event Explorer" so maybe change that?

everything else was great though! thank you so much for the speedy turn around on this!

Thank you for your thorough and valuable feedback, @kdobesh ! I've applied all of it; please take another look 🙂

[kdobesh]

looks great @janine-c thank you! Tim is OOO until Monday, but I think his will be minimal since we've been closely aligned throughout this project. nevertheless, we are going to wait til Monday to send our announcement email assuming that merging these docs won't take long after he approves it?

[janine-c]

Great, thanks for approving, @kdobesh! If you want, I can go ahead and merge it today, and I can always create another PR if Tim has more feedback when he gets back. Otherwise, Monday works great. Once I add it to the merge queue, it can depend on what else is in there to get it live, but it shouldn't take too long to get it live. Just let me know what works best for you 🙂
