/* Switch_Recent.bsh - a BeanShell macro script for displaying
* and switching between open buffers (in most recently viewed order).
* This is similar to the functionality provided by Alt+Tab in Windows.
* It is assumed that this macro is mapped to the Ctrl-Tab shortcut.
*
* Suggested shortcut: A+TAB
*
* This Script is a modification of Buffer_Switcher.bsh, written by
* Ollie Rutherfurd.
