SpeedKeys · 方向键倍速（长按加速 / 快进退 / 跳过片头片尾）

Control video playback with arrow keys — no need to drag the progress bar.

CORE FEATURES
· Hold → : speed up while holding, restore to normal speed on release
· Hold → + ↑ : switch to another speed preset (press ↑ again to switch back)
· Hold → + ↓ : lock the current speed, press ↓ again to unlock
· Tap → : skip forward a configurable number of seconds
· Tap ← : rewind; hold ← to keep rewinding every 0.5 seconds
· Auto-skip intro and outro by seconds:
intro can jump to a chosen position within the first 0-240 seconds;
outro can jump to "N seconds before the end" so the video finishes naturally
and the site can auto-play the next episode
