Press PageUp key at the video player to press the skip button (if available)
This script adds a new hotkey for the video player on crunchyroll.com.
The PageUp key can now be pressed to skip (intro, credits, ...).
If it not works, then check, if the video player element is focused by clicking into the player.
At the top of the script you can change the key, which needs to be pressed.
The script is a minimal implementation without any fancy features and can be easily edited.
