visual-studio-2010 - Can I assign the TAB key to Zen coding's Expend Abbreviation command in Microsoft Visual Studio 2010?

Question

I installed Zen Coding for the Microsoft Virtual Studio 2010.

Zen Coding v0.7 by Sergey Chikuyonok
Visual Studio Plugin v0.7 by Danny Su

I would like to be able to use the TAB key in order to use Zen Coding's Expend Abbreviation command (instead of ALT-Z) when editing HTML documents like in Sublime Text 2.

I go to Tools/Options/Environment/Keyboard and choose ZenCoding.ExpandAbbreviation but when I type the TAB key in the box to Assign the key it doesn't work.

Any idea? Is it possible?

Many thanks for your time and help.
