AIRSTEP LOOPER is a Chrome extension developed by XSONIC Inc. that allows users to easily loop their videos. With this extension, users can choose the preset "Youtube (With Looper)" and use the Looper key to control the looping functionality.

The Looper key has three functions: LOOP IN, LOOP OUT, and LOOP CLEAR. By pressing the Looper key once, users can set the starting point of the loop (LOOP IN). Pressing it a second time sets the ending point of the loop (LOOP OUT), and pressing it a third time clears the loop (LOOP CLEAR).

This extension is specifically designed to support Youtube and Bilibili platforms. However, it's important to note that the key instructions will not be displayed in full-screen mode. Nevertheless, the functions of the extension remain valid. To overcome this limitation, it is recommended to use the full-screen mode of the web page instead of the full-screen mode of the player.

Please note that AIRSTEP LOOPER requires AIRSTEP hardware to fully utilize its features.
