tmux -- any way to enable scrolling, but not selection?

Holding Shift in Konsole seems to disable sending mouse input to tmux. On OS X, (using iTerm2) @demure suggests to hold down shift + alt. https://superuser.com/a/599501/573760

due to a limitation in the protocol, it is not possible for terminal applications to only request the scrolling but not the selection. It's an all or nothing. So even if tmux wanted, it has no way of doing what you desire.

You have the following options:

• set up a keyboard short-cut that copies the tmux selection into your system clipboard
• use a terminal that supports set-clipboard function, such as xterm
• disable any use of the mouse in tmux

unfortunately, answer to your question is No

Not directly relevant to OP's case, but for anyone else arriving here from Google:

If you're using iTerm2 on macOS, this can be accomplished by unticking "Report mouse clicks & drags" while keeping "Report mouse wheel events" ticked, under Profiles -> Terminal. (Note, however, that this will also disable pane selection through clicking.)
