TVerで操作追加 is an add-on for Chrome that enhances the TVer experience. By installing this add-on, users gain access to various features including changing playback speed from 0.1x to 5.0x, toggling play/pause with a click on the video, switching to full screen with a double click, and adjusting playback speed using Q/E/R keys. Additionally, users can use the Q key to set speed in bulk, navigate the seek bar using the numeric keypad "0-9" keys, and skip forward or backward by 10 seconds with the mouse wheel.

This add-on provides a customizable experience by allowing users to toggle these functions on and off via checkboxes, offering a more convenient and efficient way to interact with TVer content.
