Quick key / shortcut key combo for switching between code view, split view, or design view

Hi,

This may sound trivial, and I feel silly, but I have been using .Net since 1.0 mostly in Dream Weaver and Visual Studios, since SharePoint I have started using SPDesigner and blend more and more, and in the whole entirety of all of this I have never been enlightened as to a quick key / shortcut key combo for switching between code view, split view, or design view, I know that you can use alt +  Tab to switch between apps i.e. going between VS to DW and so fourth; I  use ctrl + Tab to switch between open pages with in the apps i.e. say I have Default.aspx, Default.Master, Core.css, and About Us.htm; but is there a quick key / shortcut key combo for switching between code view, split view, or design view of the current page open in the app i.e. I have Core.css open in design view so I hit shft + alt + Tab and it switches to Code view, then I do it again and then it switches to Split view? Or even a setting to set these commands / properties in any of the mentioned apps (VS, DW, SPD, or B3)?

Thanks.
