xterm-keybinder

This package lets you key binds that normally terminal Emacs can not use. (i.e., C-M-g)

Summary of available key binds

Modifiers	Description
S	Space key with shift
C	[2-8] (note: xterm.el supports other key binds)
C-S	[A-Z]
C-M	"g" and space keys
M-S	[A-Z]
C-M-S	[A-Z]
s or s-S	from space to "~" (almost 8 bits characters without control sequences)
H or H-S	same as s-S, but use Hyper modifier

Usage for XTerm

You may need following configuration in your .Xresources file:

XTerm*VT100.eightBitInput: false
XTerm*vt100.formatOtherKeys: 1

Put below configuration to your .emacs

(add-hook
 'tty-setup-hook
 '(lambda ()
    (cl-case (assoc-default 'terminal-initted (terminal-parameters))
      (terminal-init-xterm
       (xterm-keybinder-setup)))))

Then start your emacs with xterm and the option

#!/bin/sh
xtermopt=path/to/this-repository/xterm-option
eval "xterm -xrm `${xtermopt}` -e emacsclient -t -a ''"

On your started Emacs, you can use C-M prefix and C-S prefix keybinds.

FYI, I'm configuring like this

Usage for URxvt

Put below configuration to your .emacs

(require 'cl-lib)
(add-hook
 'tty-setup-hook
 '(lambda ()
    (cl-case (assoc-default 'terminal-initted (terminal-parameters))
      (terminal-init-rxvt
       (when (getenv "COLORTERM" (selected-frame))
         (urxvt-keybinder-setup))))))

Start URxvt daemon:

urxvtd -q -o -f

Then start your emacs using emacs-urxvt-client file.

emacs_urxvt_client=/path/to/emacs-urxvt-client \
${emacs-urxvt-client} -e emacscliet -t &

(The main content of emacs-urxvt-client file is just a configuration to use emacs keybindings.)

Note

If you put xterm-option of this package in your xterm resource, you may have trouble because some applications already used overridden key sequences.

Contribution

I'm really beginner of xterm, so let me know if you have better idea. Pull Requests are always welcome :)
