Description nicolas.hueppelshaeuser 2012-05-05 11:50:43 UTC

I am running tmux in konsole and experience a problem when pasting text by middle mouse button into tmux.

More detailed:
When running tmux, mouse actions can be captured to change the tiling of the screen and more.  Tmux captures action of the mouse buttons, but one can "escape" this by holding shift key pressed.  So shift+mouse button results in the usual behaviour of the mouse clicks.

But not for pasting text by pressing shift+middle mouse button.
Although it works correctly in gnome-terminal and xterm, it does not in konsole.
In konsole it also activates the copy mode of tmux.

So I think this problem relates to konsole rather than tmux.

Details on versions:
Ubuntu 12.04
$ konsole --version
Qt: 4.8.1
KDE: 4.8.2 (4.8.2)
Konsole: 2.8.2
tmux of version 1.6


Reproducible: Always

Steps to Reproduce:
1. remove your ~/tmux.conf for the moment
2. start tmux (you might want to do this simultanously in konsole and e.g. gnome-terminal)
3. press middle mouse button: upper right corner shows [0/0] - tmux copy mode started
4. press left mouse button: copy mode cancelled
Steps 3&4 work correctly
5. select some text with the mouse
6. press shift+middle mouse button to paste text into tmux: on gnome-terminal the selected text is pasted into tmux, on konsole we are back to copy mode. Only after pressing left mouse button, copy mode is cancelled and the pasted text appears.

Thanks for reporting.

However, I'm quite confused by this report because I'm not a daily user of tmux.

"3. press middle mouse button: upper right corner shows [0/0] - tmux copy mode started"

Well, that is not how tmux works for me. Middle click just pastes. According to tmux(1), the default way of starting copy mode is Ctr-B-[

"4. press left mouse button: copy mode cancelled"

left click makes no change for me

" 6. press shift+middle mouse button to paste text into tmux: on gnome-terminal the selected text is pasted into tmux, on konsole we are back to copy mode. Only after pressing left mouse button, copy mode is cancelled and the pasted text appears.  "

Neither konsole nor gnome-terminal work as describled for me. gnome-terminal does to paste the text after shift+middle click. xterm does not, either.

I'm using a empty ~/.tmux.conf . Did I miss something important?

Not you, I missed something important: the line to enable mode-mouse feature.

Here we go again.
Steps to Reproduce:
1. remove your ~/tmux.conf for the moment
2. start tmux (you might want to do this simultanously in konsole and e.g. gnome-terminal)
3. Set mode-mouse on by: "CTRL-B :" now enter at the prompt: "setw -g mode-mouse on"
4. press middle mouse button: upper right corner shows [0/0] - tmux copy mode started
5. press left mouse button: copy mode cancelled
Steps 3&4 work correctly
6. select some text with the mouse
7. press shift+middle mouse button to paste text into tmux: on gnome-terminal the selected text is pasted into tmux, on konsole we are back to copy mode. Only after pressing left mouse button, copy mode is cancelled and the pasted text appears.
