Improve the key bindings further (add reckless mode)

[sayanarijit]

I like the key binding changes introduced in e0f8207 so much that I'm now considering an even stricter behavior, where an invalid key press will take you to a mode where the only keys you can use will be esc to escape the mode and ctrl-c to quit the app. This will save you from yourself when you're going too fast, recklessly.

Comments? @maximbaz

Hmmmm certainly an interesting idea, but I'm not sure if it will be more useful or annoying 🤔
But the more I think about it, the more I like.

Are you thinking even in default mode? So if I hit n instead of j to go down, then I need to esc before I can hit j?

It most certainly happened to me, not only in xplr, that for example I wanna search for asdf, I think I press / but I miss it, and then I type out the entire search term, wreaking havoc, only to realize that I didn't enter the search mode. With the strict mode, I can still be unlucky that my search term will match some existing keys, but if at least one of them is invalid, I'd be saved by the fail mode.

I'll create a similar proof of concept PR to test it out.

I think itll work best with a disable option.

Yes
