There are two ways to split the current window:

  • From the Menu Bar, go to Window - Split
  • Using the mouse, grab the splitter control found directly above the document scrollbar

But the split command only works horizontally. If you need to split vertically (see Program.cs:2 in the above picture), try using the Window.NewWindow command found on the Menu Bar at Window - New Window. Then, as in the picture above, go to Window - New Vertical Tab Group.
