Have you ever used midnightcommander (as one excample)? You could simly use the mouse and not the keybindings. But if it annoys you, just disable moused.

Is there a part in #nostr protocoll like revoking keys? i'm thinking this could be usefull if one has "lost" or made public his privat key. i'm aware that this is not a guarantie that public keys are rewoked everywhere, but at least on last used relays. as long as i understand #nostr so far.

I realy appriciate that you take the time to answer at least in short. And to be honest, i realy would like to see that bitcoin is widely addopted and not compromised in any way. I take your answers and will think a while. Thank you for your kind replys :)

Kind of, but it is not only related to bitcoin. Im not saying that bitcoin is a bad thing, but it is developed by about 1000 peoples and that is nearly the same as it is with fiat. The 21million mark may be correct, but no one has seen or proven that it will stop there or that no one will work arrount that mark. The network is running about 14 years and Nakamoto did not test this for sure. if anyone is willing to explayn or may be also prove that this both points are not an issue, i would like to listen kindly. I could read the code but it is software and as a developer i'm aware that it can be changed at any time.

If 1000 peoples develop a "free" system for about 8 billion peoples, how different would the money be in comparence to the current?

They will drop the shares in case of a bullrun, in which phase can be interesting ... but they rather buy bitcoin for exposure if this is the plan. Microstrategy has other interesting usecases in its portfolio i think.
