the event. The mouse cursor changes to the depicted image when this

editing.
Toggling an instanced operator doesn't affect its other instances.

To toggle an event (that is, turn it off and on),
click the light-bulb icon next to its name in the title bar. Turning off an
event is equivalent to turning off all of its operators and tests, although
you cannot turn the operators and tests back on individually. The event's
items do not affect the particle system, and appear as gray in the event
list. All particles entering a turned-off event are immediately passed on to
the next event, if any.
■
To make a test result always True or False, click
its icon's left or right side, respectively. The mouse cursor changes to the
first image at the left (with the left-pointing arrow) when you can click for
always True, and to the second image at the left (without the left-pointing
arrow) when you can click for always False.
