Inline Completions And Ghost Text

Developer types a function signature in VS Code. Copilot proposes a 6-line ghost-text body. Developer presses Tab.

Tab inserts the entire ghost-text suggestion at the cursor verbatim, places the cursor at the suggestion's end, and emits an accept telemetry event tied to the suggestion id so the public-code filter and metrics rollup can attribute it. The editor must not reformat or partially insert.

Developer wants only the first identifier of a Copilot ghost-text suggestion (parseRequest(req, opts)) and presses Cmd+Right (macOS) / Ctrl+Right.

Per docs, partial-accept inserts the next word from the ghost text and leaves the remainder rendered as ghost text past the cursor so the developer can accept the next chunk or dismiss. Acceptance telemetry tags the partial scope.

Ghost text shows suggestion 1 of 3. Developer presses Alt+] to cycle to the next alternative.

Cycle to the next pre-fetched alternative without a network round-trip when available; render '2/3' indicator. Alt+[ cycles backward. Esc dismisses. The accept-telemetry payload records which alternative index was accepted.
