Yes, I get similar strings.

Thanks, I prefer your solution too.

Here is an extract of emacs pc-select-mode features : 

C-LEFT and C-RIGHT move back or forward one word, disabling the mark.
S-C-LEFT and S-C-RIGHT move back or forward one word, leaving the mark behind.

[...]

HOME moves to beginning of line, disabling the mark.
S-HOME moves to beginning of line, leaving the mark behind.
With Ctrl or Meta, these keys move to beginning of buffer instead.

[...]

S-DELETE kills the region (`kill-region').
S-INSERT yanks text from the kill ring (`yank').
C-INSERT copies the region into the kill ring (`copy-region-as-kill').

In fact it behaves like the dos "edit" program I think. In addition with 
emacs standard keybindings, it's quite fine to use.

I've done a jed file doing this yesterday in 
http://www.epita.fr/~burrus_n/jed/  but I'm not very satisfied with it, I'd 
like to factorize the code. It comes with an xwindow-keys.sl which add my old 
keypad workaround (to fix), and adds Ctrl-Shift-* sequences.

Ok, I'll do it as soon as I have a little time :)
