When the analyzer is being controlled through automation, pressing this key allows the analyzer to respond to front panel key presses.
When the analyzer is in normal operation, pressing this key accesses a set of user macros, that are in the form of executable files. You can title and store up to 12 macros. When you repeatedly press this key the titles in the active entry toolbar rotate through three sets of four titles.
Note: You must already have the executable files installed on the analyzer hard disk.
