How can I fly the camera in 2.8? I want to use the fly camera navigation in Blender 2.8, but I don't know how to do it. Shift + F doesn't work. 
Thank you for your help.
The shortcut is SHIFT+` or you can use the menu View > Navigation > Fly Navigation



If you're looking for a shortcut you can search for them in the preferences (Edit > Preferences). They are searchable by name and key combination, depending what you've selected in the dropdown.
