Using the control key, and several different function keys (F2, F3, F4, F8), you can navigate through many key parts of Mac OS X with your keyboard alone.
Holding down the control key with:
- the F2 key enables you to navigate with the left side of the menu bar.
- the F3 key enables you to navigate the dock, using the left and right arrow keys to move between icons and the up and down arrow keys to view the navigate thought the contextual menu.
- the F4 key enables you to cycle through all of the open windows.
- the F8 key enables you to navigate through the right side of the menu bar. (Only works with some menu bar icons.)
Note that on laptops you must also hold down the FN key.
I have no idea how come I didn’t know about these shortcuts earlier. These are really going to come in handy, hope it helps you as well.
