Is there a keyboard shortcut in Windows 8 to view password text?
Unfortunately, there is no such keyboard shortcut :( I have looked for it repeatedly myself. The windows 8 keyboard shortcut guide on Technet (now removed for some reason) didn't contain it when I looked. Also, there are dozens of threads on the net asking the same question - none of which contains an answer. If you do discover one, let me know!
There is a shortcut in Windows 10 though1. It's Alt + F8.
