Missing Intellisense, Format Selection and Format Document for Sharepoint aspx Pages in Visual Studio 2010

I was missing Intellisense, Format Selection and Format Document for Sharepoint aspx pages in Visual Studio 2010. A colleague pointed out that if you:

select the default “Web Form Editor (Default)”

• click “Yes” to close and reopen the file

Then it should magically get pretty pretting formatting and intellisense back again. Hooray!
