Closing programs on the superbar

With vista and previous OS's it was easy to just right-click a program on the taskbar and hit the letter "c" to close it. you could very rapidly close a series of windows from the taskbar.

now in win7 x64 when i right click a program in the taskbar and hit 'c' it simply highlights the "close window" option... requiring me to either have to hit enter or click on the selected option "close window"

is it possible to have things work like they used to ?? such that a right-click and then the letter 'c' would close the window without any additional input ?

thanks in advance
