Hi, thanks for the PR, I was about to do the same :)

However, could you please change this to:

Suggested change

	tmux bind-key -T copy-mode-vi DoubleClick1Pane "select-pane ; send-keys -X select-word ; run-shell -d 0.3 ; send-keys -X \"$(yank_action)\" \"$copy_command_mouse\""
	tmux bind-key -T copy-mode-vi SecondClick1Pane "select-pane ; send-keys -X select-word"
	tmux bind-key -T copy-mode-vi DoubleClick1Pane send-keys -X "$(yank_action)" "$copy_command_mouse"

Doing so should remove the need for the delayed run-shell. It also highlights the word immediately after the double click and does not wait if a triple click is triggered but copies only when no triple click occurs.

I haven't tested this here but I have something similar in my config:

# Double LMB select word in copy mode
#
# The `SecondClick1Pane` event is fired for the second click even if there
# is a `TripleClick1Pane` key binding.
bind-key -T copy-mode-vi SecondClick1Pane \
    select-pane \; \
    send-keys -X select-word
bind-key -T copy-mode-vi DoubleClick1Pane \
    send-keys -X copy-pipe-no-clear "xclip -in -sel primary"

# Triple LMB Select Line in copy mode
bind-key -T copy-mode-vi TripleClick1Pane \
    select-pane \; \
    send-keys -X select-line \; \
    send-keys -X copy-pipe-no-clear "xclip -in -sel primary"
