Single gesture for 100% view

Is there a way to toggle between 100% and fit with either a single or reduced set of keys or mouse clicks?

This got pushed off of page 1 in about 10 minutes so I thought I would bump it once in case someone has a suggestion.

Can you elaborate? Do you mean full screen of Resolve?

I mean in a regular player window, especially in the color page. For example, quickly going to 100% to check the edges on a key and then going right back to fit to evaluate the whole frame.

map the kb shortcut to a streandeck key?

there's a kb shortcut for it, and any kb shortcut can be mapped to a number of devices, wacom softkeys, various game controlers, XKeys, Artist Color and Transport softkeys, i have it mapped to three devices currently, Artist Transport, StreamDeck and XKeys

streamdeck is IMHO an elegant answer if you do not already have anything that can trigger shortcuts

I mean in a regular player window, especially in the color page. For example, quickly going to 100% to check the edges on a key and then going right back to fit to evaluate the whole frame.

It exists in Colour Page:
Option Shift Z = 100% size in viewer.
Shift Z = fit to viewer.

Command +/- to change size in steps.

You can remap the shortcut to other keys too.

I thought everyone knew this. It's so easy to find!
Dermot suggests mapping to a controller; I use a gaming mouse with extra buttons for this exact purpose.

i have a macro that fires Ctl+f - pause - Ctl + shift +z (i think, it's been years since i've touched the kb shortcuts for this)

so one button push to put the UI's viewer at 1:1 / full screen, mapped to one of my wacom's softkeys, as i'm 99.9% of the time useing that when rotoing
