VIZ Hotkeys - For VIZ Manga & Shonen Jump is a free Chrome extension that lets you remap the default keys of VIZ Manga to something more comfortable, especially if you don’t have arrow keys. It includes keyboard shortcuts for many popular titles from VIZ, including Attack on Titan, One-Punch Man, Shingeki no Kyojin, Kill la Kill, and others. It also has a setting that lets you enable the shortcuts by default, making them easier to access.

In addition, it has a couple of other options. You can use the settings to enable/disable the hotkeys and create new ones. It also has an option to turn the key remapping on or off, so you can turn it off once you have customized it as you wish.
