Can I use double click to select and copy in tmux?

Question

I am learning to use tmux, I found when I in a tmux window, double-click to select and copy function did not work any more.

Can I use double-click to select and copy just as in iterm2?

I have googled for some time, but did not find an short and clear answer to this. I have added setw -g mode-mouse on in the tmux configure file already.

Answer 1

I found a way to achieve that: hold the option key when double clicking.

Answer 2

Don't know about iterm2, but this can be made to work in tmux 2.4 or newer
(tested on Linux w/ tmux 2.9, last command uses X11 xclip).

Added triple click to select and copy a line too.

# Double LMB Select & Copy (Word)
bind-key -T copy-mode-vi DoubleClick1Pane \
    select-pane \; \
    send-keys -X select-word \; \
    send-keys -X copy-pipe "xclip -in -sel primary"
bind-key -n DoubleClick1Pane \
    select-pane \; \
    copy-mode -M \; \
    send-keys -X select-word \; \
    send-keys -X copy-pipe "xclip -in -sel primary"

# Triple LMB Select & Copy (Line)
bind-key -T copy-mode-vi TripleClick1Pane \
    select-pane \; \
    send-keys -X select-line \; \
    send-keys -X copy-pipe "xclip -in -sel primary"
bind-key -n TripleClick1Pane \
    select-pane \; \
    copy-mode -M \; \
    send-keys -X select-line \; \
    send-keys -X copy-pipe "xclip -in -sel primary"

If you don't use copy-mode-vi, replace this with copy-mode.

Answer 3

In Alacrity holding Shift allows copying as if there's no tmux.

Answer 4

Building off of @ideasman42 's answer. This is using tmux 2.8 and pbcopy for macos mojave.

# Double LMB Select & Copy (Word)
bind-key -n DoubleClick1Pane \
    select-pane \; \
    copy-mode -M \; \
    send-keys -X select-word \; \
    run-shell "sleep .5s" \; \
    send-keys -X copy-pipe-and-cancel "pbcopy"
bind-key -n DoubleClick1Pane \
    select-pane \; \
    copy-mode -M \; \
    send-keys -X select-word \; \
    run-shell "sleep .5s" \;
    send-keys -X copy-pipe-and-cancel "pbcopy

My version briefly selects the word, copies it to system buffer and then cancels copy-mode.
