33It stays yours
The diagram behaves as one thing even though it is made of many pieces, and the script travels inside the .slate file so you can come back to it next term.
SelectTap any part to select the whole diagram, so it drags as a unit. Tap again to select the single line or label underneath — useful for recolouring one message.
EditDouble-tap the diagram to reopen its script. Change a line, press Update, and it redraws in place.
SizeWith it selected, + and − scale it evenly. Reflow to fit re-runs the layout for the board, which re-wraps labels rather than shrinking them — better for a big change.
AnnotateDraw straight over it. Your ink is separate, survives a script edit untouched, and moves with the diagram if you drag it.
DetachCuts the link to the script. It becomes plain objects you can edit and erase by hand — and can no longer be regenerated. Until you detach, the eraser will not cut through it.
ReuseCopy and paste to another board and the script comes too, as an independent copy. Edit one and the other is untouched.
