| Mar 16, 2023 at 0:55 | comment | added | oOosys | The question is how to get the mappings for the different modes? I have tried to start from the minibuffer to get its keymap, but this didn't work as expected. | |

I recommend that you go through the Emacs tutorial (C-h t) and read the manual (C-h i g(emacs)) in tandem. There is no royal road to Emacs...

The thing is that there isn't just one keymap: different buffers may have different major modes and each major mode has its own keymap. It may be that you have a buffer in Fundamental mode e.g. and the keymap for that mode does not have a binding for M-p. But if you try to do M-x something, you end up in the minibuffer which has its own keymap and in that keymap there is a binding for M-p.

@NickD : keymap called using C-h b is a great help to get an overview of key bindings. What I don't understand is why M-p is not mentioned in that list? Where I can find the description what M-p does? Calling C-h k -> M-p results in the response that M-p is not defined ... but I can get the last command retrieved using it, so it is defined ... Hmmm ...

Do C-h f self-insert-command: that's the command that's bound to most keys. Its effect is to insert the character corresponding to that key into the buffer. The basic notion is that of a keymap: a keymap maps a key (which may actually be a key sequence) to a command, so what Emacs does is figure out what key was pressed, look it up in a keymap and call the command that corresponds to it. There are all sorts of complications, but that's a decent high level view and a good approximation to the truth.
