Keyboard Layout Selector
The keyboard layout selector key allows switch to pre-defined keyboard layout/ input method when pressed. This is especially useful when there are multiple keyboard layouts enabled on the computer.
This key only works when the FlexDesigner is running. It is also only present in the Windows version of the FlexDesigner at the moment.

In the FlexDesigner
