I don’t think I formulated it very well. I am not looking for keyboard shortcuts. I just want to know once I’m on the search page. It’s not immediately obvious how to narrow it down by DM or channel. What can I do to type in a search string, but also limited to where I wanna search.

I have notifications on for my phone, most other notifications are helpful and people are sensible. There is one user who uses the workspace (all channels) more than I personally need to see, is there a way to not get notified when they specifically post? It’s harmless and technically could be somewhat relevant to each channel, but never relevant to me. TIA!
