Is there a shortcut key to switch between split panes in visual studio/management studio?

ssms, visual-studio

Solution

In SSMS: right-click toolbars, customize. Under categories, select Window, then under Commands select "Next Split Pane". Drag to toolbar. Right-click and change name to "Next Split P&ane". You can now use alt-a to change split pane.

Problem

When I have a file open in visual studio/sql server management studio and have it split in to two panes, I'd like to be able to switch between the panes without having to reach for the mouse. Does anyone know if a shortcut key exists for this?
