Copy when scrolling up

[chevalierNoir]

Is it possible to select a region by dragging mouse and then copy it while scrolling up? While holding the fn key (mac keyboard) and dragging mouse, I can select one text region and copy it. But if I scroll up a bit with my mouse (mouse mode on), it doesn't work any more. When I release the mouse, the cursor will go down to the bottom immediately and nothing got selected then copied. Thanks!

Hello @chevalierNoir 👋

Sorry for the very late answer.

To see default tmux bindings related to mouse mode, you can do

$ tmux -f /dev/null -L test list-keys | grep Mouse

You can see that the default bindings for MouseDragEnd1Pane are

bind-key    -T copy-mode    MouseDragEnd1Pane      send-keys -X copy-pipe-and-cancel
bind-key    -T copy-mode-vi MouseDragEnd1Pane      send-keys -X copy-pipe-and-cancel

With Oh my tmux!, and tmux_conf_copy_to_os_clipboard=true, you will see

bind-key    -T copy-mode    MouseDragEnd1Pane      send-keys -X copy-pipe-and-cancel pbcopy
bind-key    -T copy-mode-vi MouseDragEnd1Pane      send-keys -X copy-pipe-and-cancel pbcopy

You could use your .local customization file to stop using the -and-cancel variants, e.g.

bind-key    -T copy-mode    MouseDragEnd1Pane      send-keys -X copy-pipe
bind-key    -T copy-mode-vi MouseDragEnd1Pane      send-keys -X copy-pipe
