Bindings to restore the mouse wheel scroll behavior of tmux 1.9a?

[Kaushal]

Hi,

I liked the mouse scroll behavior in tmux 1.9a where it automatically went into copy-mode and then scrolled the pane.

How should I bind WheelUpPane and WheelDownPane to get that same behavior? 

Thanks.

> behavior?**

Try something like (not tested):

bind WheelUpPane if -Ft= '#{mouse_any_flag}' 'if -Ft= "#{pane_in_mode}" "copy-mode -u" "send-keys -M"' 'copy-mode -u'

Thanks! I tried that and it worked after I added "-T root" after bind.

I have a followup question:

- Doing a wheelup enters the copy mode fine and it scrolls the pane by pages. A single "click" of wheelup (I use discrete mouse wheeling) scrolls the pane by one "page". But the wheeldown action scrolls down by just one line.

How do I control by how many lines the pane should scroll when doing wheelup and wheeldown?

Resolved the PageDown action on WheelDownPane using the below:

bind -T root WheelDownPane send-keys npage

So far, it seems to work fine; please comment if that behavior should be configured in a different way.

The `npage` command binding works (but the result is very jumpy, unlike the default scroll behavior of 1.9a). But it is possible to control how many lines to scroll? In the source code, I see references to terms like halfpage-down and halfpage-up but I don't know how to use them in bindings.

Another related question I have is: How to quit the copy-mode if I right click on a pane? I would like to have this behavior: 

if copy-mode 

   quit copy-mode

else

   mark the pane (currently what right-click does if mouse is on)

I am simply trying to replicate the mouse-mode behavior of 1.9a.

You need to bind the key in the mode keys table:

tmux bind -temacs-copy WheelUpPane halfpage-up

(or vi-copy if you use mode-keys=vi)

tmux bind -temacs-copy MouseUp3Pane cancel

Thanks.

I almost got it working.

The only part that's not working is where I have the WheelUpPane bound to different command in  -T root and -t emacs-copy. It looks like the -T root command gets the higher priority (the binding to halfpage-up is ineffective). Can we not have both?

These are my current bindings for WheelUpPane:

# Do mouse wheel-up to enter copy mode and do page-up

bind -T root WheelUpPane if -Ft= '#{mouse_any_flag}' 'if -Ft= "#{pane_in_mode}" "copy-mode -u" "send-keys -M"' 'copy-mode -u'

# Once in copy-mode, mouse wheel scrolls scrolls by half pages

bind -temacs-copy WheelUpPane   halfpage-up

How can I fix the bindings so that when not in copy-mode, WheelUpPane enters copy-mode but when once in copy-mode, WheelUpPane does only half-page scrolls.

[Nicholas Marriott]

I think you want to move the pane_in_mode check. Try:

bind -T root WheelUpPane if -Ft= '#{mouse_any_flag}' 'send-keys -M' 'if -Ft= "#{pane_in_mode}" "send-keys -M" "copy-mode -u"'

You want your mode key binding to happen if you are in a mode,
regardless of mouse_any_flag, so remove the pane_in_mode check from the
true branch of mouse_any_flag.

You only want to send copy-mode -u if you aren't in a mode, otherwise
you want to send the key through to the mode so it'll get your halfpage
binding.

This flag checking is a bit horrible, maybe we can make it better...

That worked, thanks for your help!
I have my mouse setup as below now:
