Binding Alt-n, Alt-p, ESC-n, ESC-p

Binding Alt-n, Alt-p, ESC-n, ESC-p

[Tim Johnson]

Using GNU Emacs 25.1.1 on Ubuntu 14.04

I have no pressing need to know, but am just curious:

Alt-n, Alt-p, ESC-n, ESC-p are undefined on my emacs. 

I find no evidence of them being programmatically undefined on my
system, either with or without init files being loaded.

Why would that be?
Thanks

In which mode? I don't think there's a global binding for those
keys. Put another way: what did you expect them to be bound to?

  I had no expectations as to what they might be bound to. I
  surmised that it might be some historical issue. 
  
  Since these key combinations are so handy, one might be tempted to
  use them globally. That might mean that a subsequent utilization
  of a mode using them would get clobbered.

  Would not binding these key combinations to a mode violate the
  conventions as laid out here:

  ?

  Thanks. No big deal, just curious.

Propably. Not many keyboards these days are configured to generate
both Alt and Meta, so most bindings are on Meta.

Yes, that's always a risk with personal bindings, which is why you
have the C-c letter space.

I don't think so. That just talks about not ending a key-binding with
ESC.

  And I interpreted the documentation to read that major and minor
  keybinding recommendations are *limited* to those C-c spaces that
  are mentioned there. My mistake.
