DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

What

/terminal-setup now includes an interactive scroll-speed control for tuning mouse wheel behavior in the terminal.

Usage
claude
# Run /terminal-setup, then use left/right to adjust scroll speed
Details
  • Shows current terminal/editor scroll behavior.
  • Lets users adjust with left/right arrows, reset with r, save with Enter, or cancel with Esc.
  • Saves the selected value to user settings as CLAUDE_CODE_SCROLL_SPEED.
  • Detects terminal context such as VS Code, Cursor, Windows Terminal, xterm.js, and high-rate wheel events.
Evidence

Interactive scroll-speed UI (search for "Scroll speed", "Scroll to feel it · ←/→ adjust · r reset to auto · Enter save · Esc cancel", "CLAUDE_CODE_SCROLL_SPEED")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
