Function key

source code/utils/computerUse/executor.ts:457–475

* xdotool-style sequence e.g. "ctrl+shift+a" → split on '+' and pass to * keys(). keys() dispatches to DispatchQueue.main — drainRunLoop pumps * CFRunLoop so it resolves. Rust's error-path cleanup (enigo_wrap.rs) * releases modifiers on each invocation, so a mid-loop throw leaves

(keySequence: string, repeat?: number)

     * nothing stuck. 8ms between iterations — 125Hz USB polling cadence.
