Sorry Google, but Alt+Space is already used by Powertoys Run. At least have the decency to pick a combo that isn't already being used by your competition. So classless, but I suppose that's par for the course.
(I know the hotkey combo is customizable, but it's still offputting that they chose that one.)
PowerToys is not installed by default and neither is this Google app, obviously. It's absolutely reasonable that Google picks the most intuitive and common shortcut for an app launcher and if the user wants to maintain two or more launchers, it's up to them to configure non-conflicting keyboard shortcuts that are the most intuitive to them.
