I believe I've read about this somewhere, but I honestly do not understand what is going on with X copy buffers. If, for example, I go to KPDF and select text, then select copy to clipboard. When I subsequently go to Emacs (recent CVS) and attempt to paste using Shift+Insert, the most recent text I put into the Emacs killring is pasted into the buffer. Sometimes using the middle mouse button works for pasting external text into Emacs, but not in this case. Emacs is not the only app that behaves in an unexpected way when trying to copy and paste between apps. For example, if I take what I copied from KPDF and paste it into a Kate edit buffer, select it, then middle click in the Emacs buffer the text is inserted into the Emacs buffer. Mozilla also seems to act differently than many other apps. In particular, the location field does not copy and paste as expected. Is there a way to explain this behavior in a general way? -- Regards, Steven
