Would it be possible to make a Chrome OS compatible version of this?

Google has a github page here containing several alternative keyboards for chrome that can be installed as unpacked extensions. It even includes a ComposeKey keyboard. You could use that as a template for how to create this. It uses a json file & a javascript file.

First of all, I will admit that I should begin to click the Watch button on my own repos a lot more often. My apologies for only noticing this now, 5½ months later.

Creating entire extensions in order to accomplish Chrome OS support, seems to be far beyond my current set of skills, sadly.
