A suggestion and also a bit of a vent... why is the Expression Editor missing a whole load of shortcut buttons for various arguments/commands/functions/what-have-you? Such as Atan2, NewLine$ for strings etc. There are so many, it would be nice to just click a button and see a list. It feels like I'm just guessing at keywords I don't use much until I guess right.
Does anybody have a definitive list?
