Mosh: scroll wheel on mouse does not scroll the terminal window, shows command history instead

[jamorales-bsft]

on mac osx el capitan when I use the scroll wheel in a mosh terminal it goes through previous command as if I was pressing the up and down arrow keys. It does not actually scroll the terminal window at all.

This is expected. See #2 and #122.

I'm starting to use mosh and I've see the issue with the scroll back buffer, etc ... but even if the recommendation is to use tmux or screen, the behaviour with mosh is different than with ssh.

I've configured my remote .tmux.conf as follows:

set-option -g mode-mouse on
set -g history-limit 30000

When using ssh, I can invoke tmux and then I can scroll up/down with the mouse. If I run mosh <server> -- tmux a, I also get a tmux session, but if I use the mouse scrollbar (well, the touchpad), I see the history lines scroll by; I have to actually _enter_ copy mode (⌃b + ]) to have the trackpad work.

So there's something "else" happening there in the interaction between mosh and tmux?

@jjarava Your comment about what you’re seeing over SSH confuses me because Tmux doesn’t have any such behavior built in. Perhaps you’re using iTerm2 on macOS and what you’re seeing is its automatic Tmux integration, which can’t work over Mosh (see #640)? In any event, this is unrelated to the closed issues that you posted your comment on. If you still think this is related to Mosh, please open a new issue. Include your Mosh version (client and server), Tmux version, complete Tmux configuration, terminal application, and anything else that might be relevant—we’re unlikely to be able to help with an issue we can’t reproduce.

(I’ll delete the duplicate comment you posted on the other closed issue, since we don’t need to have two identical conversations about this—hope that’s okay with you.)
