When I do a double click, I don't see any selection. Is there anything I need to enable to make it work? Other mouse functionalities work fine. See http://www.gnu.org/software/emacs/manual/html_node/emacs/Word-and-Line-Mouse.html
Here is my mouse configuration
;; Enable mouse support
(require 'mouse)
(xterm-mouse-mode t)
(global-set-key [mouse-4] (lambda ()
(interactive)
(scroll-down 1)))
(global-set-key [mouse-5] (lambda ()
(interactive)
(scroll-up 1)))
(defun track-mouse (e))
EDIT: I use emacs through a terminal: I ssh from ubuntu terminal to a remote machine and run emacs -nw on the remote machine.
