Some elements have a blue event square/pointer on the *left* side of the element, pointing inwards (to the right) into the element. What are these used for? I thought elements emitted events from the square/pointer on the right side of elements, and received events from the rectangle tabs on the bottom.

Is there a key to identify the shapes, colors and intents of all the connection input/outputs?

The blue pins are for many purposes, not just events. They are called event pins because that is how they started. But in reality they are for all kinds of special tasks (everything except raw data exchange).

They are also much slower than other types of connections, so should be used only when absolutely needed (if you care about performance).

The blue pins on the left or right side connect directly to the bottom events.

You can technically connect left blue pin to right blue pin, or bottom left pin to bottom right pin, but that will serve no purpose in practice.

OK. To confirm: the blue pins on the left side indicate values coming *into* the element, correct?

Yes, although this input is not like other inputs (on the left side of an element). So sometimes there may be no value coming in at all. For example GainInteractor uses event input only for control of its amplitude range.
