I must have made a mistake when I reorganised the manual.

I don't know what happened to them. They were missing in 6.0. I don't
remember any reason for removing them. 'C-x u' does work, but 'C-x n'
doesn't.  I looked into it and I committed a change on 2014-06-10 (svn 
revision 5656) which deleted 'C-x n' by mistake (along with another key
binding that was deliberately being removed for a removed command).

I don't know. I would assume it was a mistake. It was like that
in every old version I checked. We should probably change it.

C-x u is bound to up-node if I'm not mistaken.

I doubt if anybody has ever carried on using it after trying it out. The 
keys are fine for scrolling as in vi or less, but experience with vi or 
less wouldn't help someone to know commands for changing the node (like 
C-x RET or C-x n).

Recently I fixed an inconsistency where M-h and M-l were the wrong way 
around for editing in the echo area.

C-c is the 'abort key' for --vi-keys (like C-g usually), but in practice 
it kills the program. In recent versions you can use ESC instead (just 
as in vi) or backspace past the start of the echo area (as in less).
