Hi Josh, do you happen to have a gamepad connected? could it be that the right thumb stick is reporting a vertical Scroll up continuosly?

I think you're right. oh my god. Apologies. I'm pretty sure this was the issue!

After realizing this, I noticed the RB button on the xbox controller tabs me over to a xaml editor in the Studio App. I found that ctrl tab does the same thing. This is super useful, you might want to add it to your shortcut documentation page!

Yeah :) the XAML editor is still a hidden feature and we recommend using our VSCode extension for this (right now available in an icon next to every asset, but in the future this will be part of a new contextual menu for tabs and assets for "Show in Explorer..., Open..., Open in VSCode, etc"

Glad to know you solved the issue!
