There is no man page that I can find.

On there documentation on their website the only tutorial I can find is for non vi key bindings.

All I can find on there related to vi key bindings is how to set them and nothing more.

I have set them in the config file but when I open nyxt and try some movements that I would expect to be rudimentary vi style navigation nothing seems to work as related to those usual bindings.

Any pointers welcome.

I wanted to try this as I have not been able to make vimb work consistently in a long time due to the shakyness of the hints - more times than not they do not show up. They will show for the front page of search engine results and then when navigating through to a page no longer work. So I had another search for other vimalike browsers and nyxt was a new kid on the block and made for hackers however have not been able to get out the gate with it yet. Vimb would probably be my preferred since it is so lightweight from what I recall but as I said poor results so gave up on it.

At the moment for keyboard browsing I am getting by mostly with firefox shortcuts which although not as streamlined as true vim style it is at least consistent for what does work so better than the lackluster vim browser experiences I have had thus far. Still in search of the consistent vim browser experience.

have you bothered searching google ?

there are a TON of "cheat sheets" and other guides

Seems you are the one who didn't bother reading the title or the post as I am asking about NYXT web browser not vim. There are certainly not a TON of cheat sheets for nyxt, specifically pertaining to vi key bindings, which is a very new browser. Vi/vim yes, nyxt no.

The manual on their site seems to be quite detailed and a good start.

They also have their own dedicated forum which seems a better place to pose/ask your questions regarding their software.
