\"clipboard\"-scheme is more consistent with what people expect from \"cut-copy-paste\". Detailed description can be found here: <a href="http://www.freedesktop.org/standards/clipboards.txt">http://www.freedesktop.org/standards/clipboards.txt</a> Now Emacs uses the old \"primary-selection\" scheme by default. --- Play with selections in Emacs and other programs (Mozilla) and observe it with xclipboard. --- Set x-select-enable-clipboard to true to change the scheme.
x-select-enable-clipboard set to t (true) in emacs-21.2-alt1. To revert to the old scheme, set it to nil. (But still I think you wouldn\'t want to do this: the new scheme fisrt tries the clipboard, and if it is empty, it follows the old scheme. And I beleive that an application that isn\'t able to copy the selection to the clipboard is not perfect -- you may use xclipbaord for such cases.)
