Who a feature applies to — the selection rule (important)

Almost every ClassNori feature applies to “the students selected right now”. The target follows from the selection automatically, so learning this one rule prevents most mistakes.

Selection	What happens when you press a ribbon button
Nobody selected	Applies to the whole class.
One student selected	Applies to that one student only.
Several selected	Applies to every selected student.

Figure 3. How the selection decides the target

The right-click menu behaves a little differently.

With nothing selected, right-clicking a card applies to that one machine (it is selected for you).
With several already selected, right-clicking a card inside the selection applies to all of them; right-clicking a card outside it applies to that one machine only.
