(Github Comment Enhancer) Emulate tab as a button or snippet

[r-a-y]

Hi jerone,

Great userscript! Was wondering if you could add a button or a snippet to emulate a tab keyboard press. I usually end up using tabs instead of spaces to add indents in textareas.

I could add a pull request. Just let me know what you prefer first.

Thanks for considering!

Interesting idea. Would be a good item for in the snippets list. :+1: I probably won't have the time to implement this myself, so a PR would be great.
