[DOCS] Environment variables reference missing `CLAUDE_CODE_DISABLE_MOUSE_CLICKS` added in v2.1.195

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/env-vars

Section/Topic

The CLAUDE_CODE_DISABLE_* rows of the environment variables table. The new CLAUDE_CODE_DISABLE_MOUSE_CLICKS variable, added in Claude Code v2.1.195 to disable mouse click, drag, and hover in fullscreen mode while keeping wheel scroll, is not listed.

Current Documentation

The environment variables reference lists CLAUDE_CODE_DISABLE_MOUSE and explains it as:

Set to 1 to disable mouse tracking in fullscreen rendering. Keyboard scrolling with PgUp and PgDn still works. Use this to keep your terminal's native copy-on-select behavior

There is no entry for CLAUDE_CODE_DISABLE_MOUSE_CLICKS, so users have no way to discover the new variable from the docs, and no way to learn that it leaves wheel scroll enabled while disabling click/drag/hover.

What's Wrong or Missing?

The release notes for Claude Code v2.1.195 announce the addition of CLAUDE_CODE_DISABLE_MOUSE_CLICKS, a finer-grained companion to CLAUDE_CODE_DISABLE_MOUSE that disables mouse click, drag, and hover while still allowing wheel scroll. The env-vars reference, the fullscreen guide, and the keybindings reference do not mention this variable, so users who want to suppress click/drag/hover without losing wheel scroll cannot find the knob through the documentation.

Suggested Improvement

Add a new row to the CLAUDE_CODE_DISABLE_* section of the environment variables table:

CLAUDE_CODE_DISABLE_MOUSE_CLICKS — Set to 1 to disable mouse click, drag, and hover in fullscreen rendering while keeping wheel scroll. Use this when you want the terminal's native copy-on-select behavior on text but still want to scroll with the mouse wheel. Pair with CLAUDE_CODE_DISABLE_MOUSE=1 to disable all mouse input including wheel. Requires Claude Code v2.1.195 or later.

Cross-reference from the fullscreen guide's "Mouse support" section so users who arrive there from fullscreen rendering docs can find the variable.

Impact

Medium - Makes feature difficult to understand

Additional Context

The release also notes that wheel scroll remains available when only CLAUDE_CODE_DISABLE_MOUSE_CLICKS is set. The current CLAUDE_CODE_DISABLE_MOUSE documentation does not mention this finer-grained split, and the new variable is only discoverable through the release notes.
