A Claude Code environment variable, read out of the shipped bundle.
It has been in the build since v2.1.195, including the newest one read.
Set to 1 to disable click, drag, and hover handling in fullscreen rendering while keeping mouse-wheel scrolling. Use this when you want wheel scroll to work inside Claude Code but don't want clicks to position the cursor, expand tool output, or open links. CLAUDE_CODE_DISABLE_MOUSE takes precedence when both are set. Requires Claude Code v2.1.195 or later

No changelog entry here has ever named it. That is a statement about what has been written, not about the name: it has been in the build since v2.1.195 without anybody writing a line about it.

No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.

One row per release since the first build this name was read out of. Absent means the build was read and the name was not in it, never mined means no bundle for that release was ever archived, and a declared type or a default is only ever what that release's own bundle stated.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the environment variable does. All environment variables.
