Macro Action Description
Note: The last “color” can be configured without “time”, and it means per-
manently displaying the last color until triggered by other macros. This macro
can be only used for BLF/BLF list feature. For more information, refer to
BLF/BLF List Key LED Status and Behavior Configuration.
EDK Configuration
To configure the EDK list, EDK user input prompt, EDK soft keys, and custom DSS keys, you have to enable EDK
