Under Edit – Bookmarks, you’ll see a disabled “Add Task List Shortcut” menu item.  This menu item becomes available whenever the task list is opened (and you’re in a project). 

Bring up the Task List – View – Other Windows – Task List  (or Ctrl+\, Ctrl+T in general development profile).  Now you can use Ctrl+K, Ctrl+H (in the general development profile) to create a task list shortcut. 

In the task list, you’ll find your task list shortcuts under “shortcuts” in the drop down.

Happy Visual Studio’ing!
