Gotcha. I didn’t notice those in particular – wish there was one for Firefox too. I built my own version of that with Keyboard Maestro and it works outside of the app environment, but only one tab at a time.
I know this is off-topic a bit, but it would be possible to run a macro/AppleScript that triggers those context menu services in another text editor, or the clipboard, then it would run a copy/paste into an obsidian document. But I see your point; the context menu needs to be enabled for a variety of reasons, including other custom services.
I was thinking some of what you’re looking for could be accomplished with Brett’s popclip extension maker, but not those specifically. And while TextExpander and Keyboard Maestro can do a lot, it’s not as simple as a right-click-and-select. So I agree; we do need contextual services enabled.
