I use a full keyboard, above the arrow keys are the fn, home, page up, delete, end, and page down keys. Whenever I’m moving quickly and go to delete something, I often accidentally hit “end”. Which jumps me to whatever “end” jumps me to, the upper left frame on the canvas, perhaps?
Anyways, when in a large file, I forget where I am so then I need to zoom out and reorient myself and go back to where I was.
I use the “Return to instance” button all the time when editing components. I would love to extend that feature when using keyboard shortcuts to change your view. So I can quickly hit “back” and then I’m back to my groove without losing too much steam.
