Yesterday, I blogged about a shortcut to hibernate a Windows XP PC (for people who are too lazy to use between 3 and 5 clicks when a double-click will do).
Keni Barwick replied with an alternative to lock the workstation (%windir%\system32\rundll32.exe user32.dll, LockWorkStation) and when I said "What about Win+L - oh yes, forgot, two fingers required ;-)" he fiendishly replied "But it’s great if you want to use no fingers… i.e. the bluetooth auto lock I’m developing :-)" - sounds a bit like a TV B-Gone for PCs to me...
