#mouse

Since fullscreen rendering, Claude Code captures the mouse — clicking in the prompt moves the cursor and a stray click can hit 'Ask something' or a menu option (very easy to do by accident in the JetBrains/IntelliJ terminal). Disable click/drag/hover while keeping wheel scroll with CLAUDE_CODE_DISABLE_MOUSE_CLICKS=1, or kill mouse capture entirely with CLAUDE_CODE_DISABLE_MOUSE=1. There is no settings.json field and no CLI flag — only these environment variables — and a running session must be restarted to pick them up.
