Copy paste; hold Shift key then select from mouse

If you press shift while doing things with the mouse, that overrides the mouse protocol and lets you select/paste. It's documented in the xterm manual for instance, and most terminal emulators copy that behavior.

oracle@localhost $ cat .tmux.conf
# Uncomment the lines with the options you want to activate (by deleting the preceding "#")

# Allow mouse interaction
#setw -g mode-mouse on
set -g mode-mouse on

# Allow mouse to select which pane to use
set -g mouse-select-pane on

# Allow mouse dragging to resize panes
set -g mouse-resize-pane on

# Reload tmux config
bind r source-file ~/.tmux.conf

#set -g status-right '#[fg=yellow]#(cut -d " " -f 1-3 /proc/loadavg)#[default] #[fg=white]%H:%M#[default]'

On unix you can also use alternatives like screen or  gcm.
