Thanks @anon63144152 for making me aware of that link. Since I didn’t see the answers to my questions, I then proceeded to resolve most of them myself, and posted a reply on the other thread. See link below:
I’m also glad @WhiteNoise resurrected the FR, so that it might evolve into something which in the future would render these queries useless, as one could then do a search for say cmd + p.
Finally I found, that occasionally, and I don’t why or when, Obsidian does actually report where the conflicting hotkey is. Alas, it completely fails, when some idiotyou assign the same key combination to more than two commands.
So, all in all, I reckon I’m good to go, and still hoping for the FR to be resolved.
