This will let you use other keys like Arrow keys, Enter key, etc. to be used as shortcuts. They are very handy keys and can be used in a lot of places.

For example, on Instagram, there are posts with multiple images. There are left & right arrow buttons given to change the images, but we can create web shortcuts for those buttons and use the Left & Right Arrow keys to click on those two buttons respectively.

Note: The above functionality won't work as desired with other keys right now, not because of keys, but because the extension is currently missing a feature regarding how to react when there are multiple similar elements, for example, the Like buttons in a social site is present in multiple numbers in a single page and the extension will only click on the first one, doesn't matter how much you have scrolled through.

The other one is Keybindings, which are the usual keyboard shortcuts we use at other places, like Ctrl + C, Alt + S, Command + Shift + V.

They can be used on websites where single-character key shortcuts won't work well, for example, text editing & notes sites like Notion, etc.
