Oh, that's a good tip... ty..shouldn't it be T/R by default...some of the options on this platform, whether the real F18 works this way or not, have an annoying habit of resetting themselves to the default, when it is clear the setting you last had is more conducive to handy operation...like, for instance, how the TDC cursor bars snap back to its park position instead of staying in the same area of the screen you last had it...
