Usually this combination opens small sub-menu in the mouse position wchich allows to choose zoom values like fit to screen, 100% or 200%. It wordk on Windows, but when i moved to mac, the sub menu is showing and dissapearing milisecond later.
Thanks! I didn't know combination with "opt" key. That works. I am mac user for couple of monts, so I'm very used to "windows solutions" But it would be great and handy in use If Adobe fix "spacebar and click" only.
