Could you make the space bar(or any keys so I can control it in the keyboard shortcuts) to work as in Photoshop?

In Photoshop, space bar works only while it's pressed, then go back to a previous tool automatically.

I have to hit a tool key just in order to go back to the previous tool whenever I move the screen using zoom navigator. I think it's really unnecessary.

If there is any specific option for that already, please let me know it

thanks.

You can hold down Alt-LeftClick to pan the screen, Alt-RightClick to zoom, and Ctrl-Alt-LeftClick to rotate the view without switching tools.
