Cannot copy/paste in integrated terminal running tmux

[rmgpinto]

In my terminal, Alacritty, I simply select the text I want to copy and the selection goes automatically to my clipboard.
It doesn't work in VSCode's Integrated Terminal running tmux.

I've tried the following options without success:
"terminal.integrated.macOptionClickForcesSelection": true
"terminal.integrated.rightClickBehavior": "nothing"

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.87.2 arm64
• OS Version: MacOS Sonoma 14.4.1

Steps to Reproduce:

1. open VSCode
2. open Integrated Terminal
3. run tmux
4. try to copy-paste text with mouse

My tmux.conf:

set  -g default-terminal "screen-256color"
set -g status-keys vi
set -g mode-keys   vi
unbind C-b
set -g prefix C-a
set  -g mouse             on
setw -g aggressive-resize on
setw -g clock-mode-style  24
set  -s escape-time       500
set  -g history-limit     2000

I think you're looking for this? terminal.integrated.copyOnSelection

it works on VSCode integrated terminal, but once I start a tmux session it doesn't work.

I am also seeing this on Ubuntu 22.04.04, vscode 1.88.0, tmux 3.2a

Holding down shift while selecting works though.

I'm seeing this also on vscode 1.89.1 tmux 3.3a on mac in remote session to linux. I can't seem to select text with mouse using any combination of modifier keys.

Interestingly, in my case I can select if I am using tmux inside vscode integrated terminal inside a bottom pane of original window.
But once I move it to a detached window using "Move Terminal into New Window" I can no longer select text.
If I drag that terminal back into bottom pane of original window then I can select again.

Note related issue was reported and fixed in earlier vscode in #192518.

In my case I found that "terminal.integrated.macOptionClickForcesSelection": true allows me to select in detached window also. It still seems weird that behavior is different between in-pane and detached though...

[studgeek]

Actually, I do still see a behavior difference between once a terminal is detached.
When in pane I can mouse select text with no modifier key. Once detached I can't select with no modifier key. I have to have "terminal.integrated.macOptionClickForcesSelection": true and also press Option to select.
If I move terminal back in pane then I can select text with no modifier key again.

As to copy the shell commands, I use emacs ~/.bash_history in tmux.
