Type-ahead keystroke queue
Keep typing while the host processes Enter and function keys—OL Terminal queues keystrokes in order and drains them when the session unlocks.
OL Terminal type-ahead queues keystrokes while the host is processing action keys (Enter, F1–F24, Page Up/Down). When the server responds and the keyboard unlocks, queued input is applied in the original order so users do not lose typing during slow round-trips.
