How to get Nvil to Paint select like Rocket3F?

It seems no matter what I do, I'm limited to a marquee style selection in Nvil. I would like to be able to paint my selections like in Rocket 3F. I went through both Streamline tools but can't seem to figure out how to make it work in Nvil. Any suggestions?

For me, I just hold 'x' and paint to select. Not sure if this is a default binding or if I customized it.
Try it.

Thank you, that worked. Streamline Tools seems to indicate that paint select is tied to the "Q" keyboard shortcut.

Yep, default Nvil is the X key.

Andrei might of changed it in Rocket to Q.

Pretty easy to change the keybindings in Nvil just go to Edit > Customise > Tools and search for "paint select".
