I did a bit of research to understand why I could not use my mouse to drag to select text to copy to the clipboard in iTerm. Apparently https://github.com/openai/codex/pull/641 to enable mousewheel scrolling broke this functionality. It seems that, unless we put in a bit of effort, we can have drag-to-select or scrolling, but not both. Though if you know the trick to hold down `Option` will dragging with the mouse in iTerm, you can probably get by with this. (I did not know about this option prior to researching this issue.) Nevertheless, users may still prefer to disable mouse capture altogether, so this PR introduces: * the ability to set `tui.disable_mouse_capture = true` in `config.toml` to disable mouse capture * a new command, `/toggle-mouse-mode` to toggle mouse capture
