The calculator crash when this key is pressed and if an app like rpn, reader, or other, is not present so will use the constant APPS_CONTAINER_SNAPSHOT_COUNT to know index of settings.
Note : I haven't tested the case where it could always select the last of apps, if there are external ones. I don't know if this variable also counts external apps, but I see it used above, so why not use it.
EDIT: I tested this case and is work perfectly, the key always open settings even 1 or more apps is not present. 😉
