Alt Key Does Not Work Using Terminal Emulator

This situation has been seen with the Exceed terminal emulator from Hummingbird. It is likely to be seen with other emulators.
Solution - Examine the configuration dialogs for your terminal emulator. Exceed allows you to assign one of your Alt keys for windows use and the other for UNIX emulation. Once you have configured your terminal emulator you will have normal Alt key operation with the 4Test editor.
