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.

Keybindings that terminals cannot tell apart are rejected

Useful3 Signal2
Terminal UI not in their notes

Binding ctrl+[, ctrl+i or ctrl+h is now an error since terminals send them as Escape, Tab and Backspace.

ctrl+[ctrl+ictrl+h
What

Binding ctrl+[, ctrl+i or ctrl+h is now an error, because terminals send those as Escape, Tab and Backspace and Claude Code cannot distinguish them.

Details
  • Reported at severity error, so the binding is rejected rather than warned about.
Evidence

Cannot be rebound - identical to Escape in terminals

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