Answer by Michael Paulukonis for Where is Developer Command Prompt for VS2013?

I used a modified version of this answer - based on my experiences adding it to VS 2010:

1. Select Tools>>External Tools in Visual Studio
2. Click Add
3. Title: I use Visual Studio Command &Prompt
   • &P Makes P a alt-shortcut key (when menu active)
   • I originally used C, but that conflicts with the existing shortcut for Customize
4. Command: C:\Windows\System32\cmd.exe
5. Arguments: \k "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\vsvars32.bat
   • /k keeps a secondary session active so the window doesn’t close on the .bat file
6. Initial Directory: I use $(ProjectDir) (from the dropdown)
7. Click OK.

Now you have command prompt access under the Tools Menu.
