Yes, I’ve just been warned by Mr Dongo for an innocuous post. Maybe we’re not nasty enough? 
I suppose if the board just wants humourless nodding dogs that’s what it deserves.
To the OP Trip is a funny one and I spent some time tracking it down looking for the “Trip” button. Simply (and for others if you’ve already sussed it but haven’t got the hang of search) go into the presets and scroll down to the "T"s (and on to TR… etc) and you’ll find a couple of the more obvious Trip examples there.
And frankly, I think the current system is too frickin’ convoluted for its own good
Definitely in some areas it’s over engineered. I have to be careful what I say apparently as there is a forum apparatchik on the loose warning people about saying that and threatening “suspension”. Common sense is, apparently, not allowed. Especially if one has read a book.
