Wait a minute...
That's hardly using the Win key alone.
In Win 7 you can get to sleep mode on a laptop by doing the following:
1 Click the Windows key
2 Use the trackpad to move the cursor to the shutdown button.
3 Click the arrow next to the shutdown button to call up the options
4 Click on sleep
In Win 8 you can get to sleep mode on a laptop by doing the following:
1 Click the Windows key + I
2 Use the trackpad to move the cursor to the power button.
3 Click Power
4 Click on sleep
There are still the same amount of steps in Win 7 and Win 8.
Of course, I set my power button on my laptop to make it go to sleep faster. Slide it to the right and release puts it to sleep. (Win 7 or Win 8)
Alternatively, in Windows 8 you can do the following.
1 Get to the desktop (Win or Enter key )
2 Press Alt + F4
3 Choose Sleep
4 Click OK
I don't think either way (Win 7, Win 8 A or Win 8 B) are any easier. They are just different.
