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!
