Some of us would prefer to navigate the Windows OS using just the keyboard, some of us may at times lose mouse functionality, or some of us might just be having a lazy day and that extra mouse maneuver is a bit much. Whatever the case, how do you enter into the address bar using the keyboard and bypassing an endless amount of tabbing?
Windows Explorer: F4, Alt + D
Internet Explorer: Ctrl + L, Alt + D, F6
Chrome: Ctrl + L, Alt + D, F6, Command + L (Mac)
Firefox: Control + L, Alt + D, F6, Command+L (Mac)
Safari: Command + L
Rarely spoken of but very convenient, give them a try.
