Which combination of keys is C-enter? Ctrl+Enter?

Same behaviour here for Ctrl+Enter.

URxvt.keysym.C-Return:
it seems to use this, but this setting is not correctly!

haiyuan_victor · 02-16-2012, 06:44 AM

the manul page says:
URxvt.keysym.C-Return: \033<C-Return>

but, i add this to my .Xresources, it can not work either

What about /etc/X11/app-defaults/Urxvt ? Dunnot which Linux you have but somewhere about there in etc, have you tried to edit there instead?

It works for me after adding this line to ~/.Xresources (but not until I had rebooted. Logging off and back on would probably have been enough):
URxvt.keysym.Control-Return: \033<Control-Return>
"C" could have been used instead of "Control".

Testing at a command prompt:

Code:

c@CW8:~$ ^M
[above by using Ctrl+V then Enter]
c@CW8:~$ ^[<Control-Return>
[above by using Ctrl+V then Ctrl+Enter]
c@CW8:~$ urxvt -help
rxvt-unicode (urxvt) v9.12 - released: 2011-12-05
[snip]

EDIT: maybe that didn't work! Maybe it should have shown ^[^M. But it demonstrated that .Xresources is effective.

Now using xrdb ~/.Xresources and starting a new urxvt instance instead of logging off and back on (there had to be a better way!) ...

It seems urxvt is taking <Control-Return> as a literal string instead of substituting Control-Return's value:

Code:

c@CW8:~$ read -r
[pressed Ctrl+Enter] 
^[<Control-Return>
c@CW8:~$ echo "$REPLY" | od -a
0000000 esc   <   C   o   n   t   r   o   l   -   R   e   t   u   r   n
0000020   >  nl
0000022

If the input required by emacs is Escape followed by ^M, a workaround is possible using URxvt.keysym.Control-Return: \033\015
After setting that and re-initialising:

Code:

c@CW8:~$ read -r 
^[
c@CW8:~$ echo "$REPLY" | od -a
0000000 esc  nl
0000002
