Animate CC HotKey Brush Settings

I'm using the default brush with pressure sensitivity turned on as well as tilt

max: 8

min: 1

Things go well when I draw the character's main outlines, but this: Zoom in with stage

is the bane of my existence.

I have to turn it off every-time I want to draw with a smaller brush size. Why?

1 should be 1 pixel no matter how zoomed in your camera is. so inconsistent.

Anyway It'll take some time getting used to, but my question is:

     Is there anyway to hotkey zoom in with stage?

I find It so un-immersive stopping my drawing and clicking something with my mouse just so I can draw the same frame's smaller details.

PS: If anyone has any advice on how they have their drawing station setup, that'd be really helpful!
