additional key bindings for xterm

additional key bindings for xterm

[Dan Nicolaescu]

xterm-216 when run like this:

xterm -xrm '*modifyOtherKeys:1'

emits distinct strings for key combinations that did not do anything
in the past, for example C-. C-, C-TAB C-return 
This allows emacs to use these keys when running in such an xterm. 
For example the C-. binding in flyspell-mode was only usable in X, but
not in a terminal in the past. 

What other keys would be useful for emacs to support? Please give
specific examples so they can be added to term/xterm.el

Thanks

Certainly the control versions of all the printing characters
are useful.  The control-meta versions of them may be useful too.
Beyond that, probably nothing is actually used much.

On the Linux console, I've been using the following (as
additional modifiers with appropriate additions to the console
keymap:

C-'          Hyper
c'           Super
C-,          Alt

In addition I also change the windows keys to hyper and super.

The trick on the console is to make these keys generate the
strings C-x@[h|s|a] -- little known Emacs feature I discovered in
some corner of the info docs once --- and never found again.

Start info, go to Emacs, then to User Input.

It is mentioned near the end of that node:

,----(excerpt of: info: Emacs: User Input)
|  If your keyboard lacks one of these modifier keys, you can enter it
| using `C-x @': `C-x @ h' adds the "hyper" flag to the next character,
| `C-x @ s' adds the "super" flag, and `C-x @ a' adds the "alt" flag.
| For instance, `C-x @ h C-a' is a way to enter `Hyper-Control-a'.
| (Unfortunately there is no way to add two modifiers by using `C-x @'
| twice for the same character, because the first one goes to work on
| the `C-x'.)

The arrow keys are already available in xterm in all variants even without
modifyOtherKeys.

What other keys _wouldn't_ be useful?

On a Linux tty, I have unique keycodes for <left>, <right>, <up>,
<down>, <insert>, <delete>, <home>, <end>, <PgUp>, <PgDown> with all
combinations of C-, M-, <shift>.  I currently have most of them bound.

I certainly think the arrow keys should have distinct codes for all 8
modifier combinations.
