Each event is in the domain of the transition function belonging to the "current" node, where the function's range is a subset of the nodes.
每个事件都在属于“当前”节点的转移函数的控制范围内，其中函数的范围是节点的一个子集。

Once you have afunction call that can operate on arangeof lines, a particularly useful technique is to call that function via Visual mode (see: help Visual-mode for details).
You've got a picture of somebody's face, it's a million pixels. Each pixel has arangeof values from zero to 256. I want to hash a face with some function into an integer.
