Split edit window in Visual Studio

Solution 1:

I think what you want to do is to add a new vertical tab group. The keyboard shortcut to do that is

Alt + W, V.

According to this source, it works for Visual Studio 2005, 2008, and 2010. In my experience, it also works for Visual Studio 2013.

Solution 2:

Another easy option is to open two documents, then just click and drag the tab for one of the documents and drop it on the document itself. This will display a menu that lets you move the document to a new vertical or horizontal tab group.

I find this to be the easiest and quickest way to do this.

You didn't ask in the question, but if you want to edit one document in two windows, you can grab the small area above the scrollbar and drag it down. You will now have your document open in two scrollable areas. Great for working on two sections at once.

Solution 3:

To create a keyboard shortcut for "Window->New Vertical Tab Group" you need to assign a shortcut to "Window.NewVerticalTabGroup" command.
Tools->Options->Environment->Keyboard, in "Show commands containing" type "Window.NewVerticalTabGroup", and assign the keyboard shortuct in "Press shortcut keys" field.
Remember to click "Assign" before "OK".

Solution 4:

For Visual Studio 2012:

Move your mouse over the Class tab > Right Click on the Title of the Class > New Horizontal Tab Group or New Vertical Tab Group.

If you want to split the same class: Tools -> Options -> Environment -> Keyboard -> search by Window.Split and add a new shortcut.
