My bad, my slang was a little arcane.
In electronics, a latch that is set (triggered) by the fact a signal changes is called edge triggering.
A latch that is set by the state of a signal is level triggered.
Generally, a positive level triggered flip-flop’s output will follow its input as long as the triggering signal is positive.
A positive edge triggered flip flop captures the input state on the transition. Once the edge occurs, the output is set. Further changes on the input are ignored until the next positive-going edge.
Edge triggered flip-flops take a snapshot on the edge. Level triggered follow the input while the trigger signal is valid.
