Nearly every function familiar to most desktops is somehow different in GNOME Shell. So, navigating the UI with a keyboard might feel more efficient than hunting around with a mouse. Thankfully, there are a lot of handy keyboard shortcuts available in GNOME 3.

Application Switcher
Hopefully you've picked up on the fact that GNOME 3 has no on-screen task management, and the Activities overview is somewhat of a hassle. Fortunately, there is a new application-based Alt-Tab switcher.
The Application Switcher can be activated without auto-cycling through windows by holding down the Alt and ~ key. Being application-based (not window-based), the Application Switcher combines multiple windows of the same application into a single icon. Pressing the down arrow over an application icon displays thumbnails of all windows created by that application. You can use the right and left arrows to cycle through applications and windows.
The Application Switcher
Although this isn't a suitable replacement for on-screen task management facilitated by taskbars and docks, it can help shave off time you'd otherwise spend fooling around with the Activities Overview. Then again, keyboard shortcuts are never a sufficient remedy for UI design problems.
Mouse
If you really rely on a mouse for navigation, you're not entirely left out in the cold. Despite the extra burden that GNOME Shell hits you with, there are a few helpful mouse tricks.

Scroll Wheel Down over Window in Activities OverviewZooms out window preview
Zoom Windows In The Overview
The Windows section of the Activities Overview can quickly get confusing if you have multiple windows of the same or similar applications open at once.
Which one was I looking for?
Using the mouse scroll wheel over any of the windows in the Overview zooms in on it for greater detail. This comes in useful if you find yourself with multiple visually-ambiguous applications open. Text editor and terminal junkies are sure to find this trick essential.
Ah, there it is!
Hidden Minimize
While GNOME 3 ditches the minimize and maximize buttons, right-clicking on window title bars brings up a menu that contains the option to minimize applications.
Hidden Minimize/Maximize Controls
This appears to be the only way to minimize applications in GNOME Shell by default. With no task bar to speak of, who knows where they actually go? The window still appears in the Activities overview. But apparently, minimizing windows in GNOME 3 simply causes them to disappear from the windowing area.
Touchscreen
Unlike Canonical, which developed the fantastic uTouch gesture language, the GNOME project is working with Qt and X.org developers to bring modern multi-touch support to all of Linux. There is no telling how long this will take. But many of you may have noticed how large screen elements like window title bars and the close button have become.
