I use the "LOAD" command.
Make a skin for the app You would like to run. ( say, OBDII.skin)
Should include OBDII_OFF.jpg, OBDII_ON.jpg, OBDII_DOWN.jpg, OBDII_EMPTY.jpg. (atleast the OFF.jpg and ON.jpg)
Then assign a button on the Menu to perform that function.
You can also use the "LAUNCH" command. But this is how I usually do it.
Hope that helps.
