Windows 8 introduces a new feature called Password Reveal. While using Windows 8, whenever you enter your password in the password field of a Windows 8 app, IE 10, or the login screen, a Password Reveal Button or icon will appear at the end of the password field. When you click on this button, your password gets momentarily displayed in place of the bullets/asterisks. It is a very useful feature, especially when you suspect you might have mistyped a character (e.g. if you held down shift one character too long or had num-lock off etc.) and you just want to confirm before clicking on the Sign in or Enter button. (Of course you would only use this when you sure no one is behind you)
My question is this: is there a keyboard shortcut (e.g. Ctrl+R) to reveal the password, so that it can be done quickly and efficiently without taking your hands off the keyboard to use the mouse to click the button.
It seems to me that this would be an obvious feature to add, given that standard text boxes already respond to a number of keyboard shortcuts (e.g. Ctrl+X) and that moving your hand off the keyboard to use the mouse and move it to target the small icon is incredibly inconvenient, especially when you only need to see the password for a fraction of a second to confirm it.
EDIT:
As described in the answers below, Windows 8 apparently had no such shortcut, but there is a shortcut in Windows 10. It's Alt+F8.
