C-M weirdness when running Emacs within an Xterm

C-M weirdness when running Emacs within an Xterm

[Mike Irwin]

When I run Emacs within a Xterm, I'm unable to use any keybindings that use a
C-M combination.  Emacs acts as if it didn't receive the M bit.  Keybindings
that use just C or M work fine, though.  Is this an Emacs or Xterm issue, and
how might I resolve it?

The latter.

You probably can't, unless you can modify your keyboard configuration
to produce key codes that distinguish between C-<key> and C-M-<key>.
The way to do that is system-dependent, so please describe your system
in more detail.

I'm running Emacs 21.3.1, Bash 2.05b, XFree 4.3, Gentoo Linux 1.4, TERM=xterm.

I forgot to mention that the keymap I'm using is a modified us.map in which
I've changed Caps_Lock to send Control.  As for X, here's the relevant parts
of XF86Config:

Option "XkbRules"   "xfree86"
Option "XkbModel"   "hp2505"
Option "XkbLayout"  "en_US"
Option "XkbOptions" "ctrl:nocaps"

I'm using hp2505 since it seems to work well with my Dell Inspiron 8500
notebook.

Does this happen for all keys, or just for the non-letter keys?  That
is, does C-M-f work as described?

Like Eli says, it is normal for C-M-<right> and C-M-<f2> to fail.
