Thanks for the suggestion. I'll looked into the "goNext" and "goPrevious" commands, but theier use case is different from "Increase/Decrease URL number". I guess this is what you are looking for: https://github.com/Robbendebiene/Gesturefy/issues/277

Vimium uses user specified patterns and strings and then searches the website for a match. This means users have to contantly extand the list for every website that currently does not match. This is the only reliable solution sofar, but it's not user firendly. Thats why I decided that this command will only be available as a user script (once user scripts arrive in Gesturefy).

I Hope you understand my decision.
