This could solve something I've been trying to solve. But not as-is. I want users to be able to add extra spacing between words very easily. Without BBCode or CTRL+key, ALT+key, combinations. I just want a regular spacebar press to insert a non-breaking space. I tried modifying this extension to do this, but I failed to get it working. 😅
So, if you ever get bored and can add a way to make any keyboard key insert something (instead of only the ALT+ options) that would be amazing. Or a new mini extension. In other words, when keycode 32 (spacebar) is pressed, insert unicode U+00A0
"non-breaking space."
I guess you'd have to be really bored though to do this because this would only be useful for a few people; maybe only me. 😃
