emacs - some navigation keys aren't working

[Daniel Dalton]

Hi,

A few of my navigation keys in emacs don't appear to be working, for
example meta (alt key), shift and , to go to the top of the file does
nothing. Same with bottom of file. It seems to work fine when it is ran
from x though. Used to work fine, before my holiday, not sure what has
changed. I've done a few updates and perhaps something else to cause
this issue, but I'm not sure. so does anyone know what I've done? Has
the keymap or layout settings been changed? I'm not sure why it works in
X and not on the console? Any ideas? 

Thanks,
Dan.

X11 can use "synthetic key events" which inside a terminal emulation  
are not available. And some terminal emulations even offer less than  
others... And the rich ones can be artificially restricted when  
giving them the wrong terminal capabilities.

C-h b shows all key bindings available in this major-mode. With C-h k  
you can check whether GNU Emacs sees the key combination. Then you  
can sort your own key bindings into those which work only in a  
windowing environment and those which work always.

Ok, thanks.

This did the trick. 
loadkeys /usr/share/keymaps/i386/qwerty/us.kmap.gz
(As root)

Hopefully it stays on next reboot:p

Thanks,
Dan.

X delivers key events, the console character sequences.  If your console
has no character representation for a certain key combination, there is
no magic Emacs can engage in for finding out the key presses.
