If you are running A-Shell/Windows or ATE, and you are using multiple instances of ATE or A-Shell, you may use the keyboard combination Ctrl+Tab to toggle between those sessions.

In the event that you are using A-Shell with PolyShell (an A-Shell add-on that you don't need to know about unless you are using it) and your miami.ini file contains the phrase POLYKEY=` (grave), then you may also switch between ATE sessions by use of the grave key. This option has been thoughtfully added for those dexterity-challenged users who can't master the multi-finger coordination necessary for Ctrl+Tab, or who might be used to and prefer to use the typical Polyshell hot key. 

Note also:

•   Minimized windows are re-displayed by Ctrl+Tab, and skipped by ` (grave) .

•   The grave key is activated only by the server for ATE; for local Windows sessions, it depends POLYKEY=` in the local miame.ini.

Note: "Scrollback" is also used in the ATE doc. Make sure changes get copied there.
