Source Intelligence

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.

Ctrl+letter works on non-Latin and alternate keyboard layouts

You'll notice
Useful4 Signal2
Terminal Input

Ctrl+letter shortcuts now work on Cyrillic, Greek and other non-Latin keyboard layouts.

What

In terminals using the kitty keyboard protocol, Ctrl combinations now resolve from the base-layout codepoint the terminal reports, so Ctrl+letter shortcuts work on Cyrillic, Greek and other alternate layouts instead of being dropped.

Details
  • When Ctrl is held and the reported codepoint is above 127, the key is resolved from the base-layout alternate codepoint.
  • The modifier field is now read from the correct position in the escape sequence.
Evidence

u = l[4] ? parseInt(l[4], 10) : 1,

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