Create a keyboard shortcut to focus on the 3D viewport

As a Roblox developer, it is currently too hard to move the focus to the 3D viewport using the keyboard.

If Roblox is able to address this issue, it would improve my development experience because when testing my game in Studio, I often have to interact with the Command Bar and then focus back on the 3D viewport.
As my game uses the mouse a lot, I can’t switch from one window to another within Studio using the mouse.
I have already figured out that there is a shortcut (Ctrl+9) to change focus to Command Bar.
But then, there is no keyboard shortcut that brings the focus back to the 3D viewport. So I have to use the mouse and then I lose the original mouse position in my game.
