Windows clipboard and Emacs yank, kill-region, and kill-ring-save

Windows clipboard and Emacs yank, kill-region, and kill-ring-save

[Tim McDaniel]

I have updated my packages to the latest versions.  I have long had
installed
- emacs
- emacs-X11
- emacs-el
- xemacs-emacs-common
- X11

In Emacs, ^Y is the default keystroke for the basic "yank", to paste
the contents of the most recently element of the kill ring (the text
most recently cut or copied in Emacs).  Until some time in the past
few weeks, I am 80% sure that ^Y would grab out of the Windows
clipboard -- that is, I could copy in Windows using ^C or Ctrl-Ins,
and then use ^Y in Emacs to paste it.

But I think that sometime in the last few weeks, perhaps with the
end-of-July update of Emacs in Cygwin, it stopped working.  Now, ^Y
only pastes what was killed (or copied) in Emacs.  Similarly, if I
kill or copy text in Emacs, it's not put into the Window clipboard.

Any Emacs users out there?

Am I misremembering the old behavior?  At home I use Linux, and there
the X clipboard and Emacs clipboard usually work together (modulo
X having more than one).

If I'm not, did something change, and can I do some setting to obviate
it in Emacs?

There have been some changes in how emacs handles selections, starting 
with emacs-24.1.  Look at the NEWS file ('C-h n') and search for 
"selection changes".  It describes the changes and tells you how to 
restore the old behavior.

Yes!  The important one for me is

(setq x-select-enable-primary t)

Thank you very much for the quick and informative answer!

Are you talking about X11 emacs, or emacs in a terminal?

I have this in my ~/.emacs file on both Linux and Cygwin:
(setq x-select-enable-clipboard t)

I see in the news file that it's now set by default.
It has always worked in graphical emacs but has never
worked in a terminal on either Linux or Cygwin.

But I sure would like it to work in a terminal.  Are you
able to paste clipboard text in emacs in a terminal?

When I run emacs in mintty, I can paste clipboard text with Shift-Insert.

Ah!  That works!  Thank you.

But there are still a couple problems.

1) Shift-Insert is a huge improvement, but is still a little
    clunky.  I'd like to tie it to Shift-Ctrl-Y, but when I
    press CTRL-h Shift-Insert, the *Help* window cryptically
    reports, "T runs the command self-insert-command".  What
    command is actually running?

2) How can I go the other way--copy from emacs in a terminal
    to the Windows clipboard?

"T" was probably the first character of the text you pasted.  I think 
it's mintty that processes the Shift-Insert; emacs never sees it.

Select it with the mouse.  Again, it's mintty that's doing the copying 
here; emacs doesn't see the mouse operations.

In mintty, you can enable Ctrl+Shift+letter shortcuts including
Ctrl+Shift+Y for Paste on the Keys page of its options.
