HTML Comment-out Add-In

Here is an old add in to quickly comment out HTML code. Maybe I am missing it, but it seems like there is a shortcut in VS2010 to scratch your tail with one click but commenting out HTML code is still awkward as hell.

What's the 开发者_开发问答easiest way to get a function like this working?

Can I expect any add-ins that were written for older versions of VS to work in VS2010 w/o an upgrade?

Visual Studio's Comment Selection command (Ctrl + K, C) works with HTML.

You can also press Ctrl + K, U to uncomment.
