Per-screen anchoredKeys option keeps specified keys and combos local on the server instead of relaying them to clients. Supports single keys (F13, Delete), modifier combos (Alt+Tab, Ctrl+A), and arbitrary VK codes via a 256-bit bitmask. Combos use a pending-modifier mechanism that holds modifier keys until the next keypress determines whether to anchor locally or flush to the client.

Repurpose unused lParam bit 30 to carry LLKHF_INJECTED so the combo handler can distinguish physical keypresses from its own SendInput events. Prevents infinite re-entry on combo repeat and modifier-UP paths. Keys that are both combo triggers and bare-anchored now enter the combo state machine correctly instead of short-circuiting. Combo state is cleared on mode transitions to prevent stale holdover. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
injectComboLocally fired a full down+up cycle on every keypress, causing held keys to produce rapid press-release instead of a sustained hold. Split into injectComboLocally (downs only) and releaseComboLocally (ups on physical release). Extracted sendInputToTarget to share the foreground-flip logic. Added !isInjected guard on trigger-UP path to prevent infinite SendInput loop. Combo state cleanup on mode transitions now includes g_firedModCount.

VK_CANCEL wrapping in sendInputToTarget so injected events bypass the hook instead of being relayed to the client. Clear g_keyState on mode change to prevent stale modifier state. Remove isInjected guards that blocked pedal (SendInput) events from releasing combos. Order-independent trigger buffering for simultaneous key arrival.
