Turns out Google has been doing this for my own site on certain pages. If I search for:
devtools capture element screenshot
It has listed the exact instructions on the search results page: https://i.imgur.com/NTdDjZY.png
Can I get an outsider perspective, are those 4 list items shown in the rich snippet too many? Is it too wordy? I'm wondering if a single item which said:
Search for screenshot in the Command Menu (Cmd + Shift + P)
Would be better?
