actions

Actions are a very complex portion of the spec. Some preliminary understanding of concepts is useful:

• tick: a slice of an action chain. Actions from different input sources can be executed simultaneously. These are first lined up from the first action. Every vertical “slice” across the different input sources’ action lists is a tick. A tick is not associated with any particular time value, and lasts as long as the longest action duration inside the tick.
• input source: a representation of an input device like a keyboard, mouse, finger, or pen. There can be any number of input sources. Each one has its own id.
• action: a behavior performed by an input source. Different types of input source have different types of possible actions

The command takes a list of input source actions. In other words, a list of objects, each of which represents an input source and its associated actions. Each input source must have the following properties:

• type: String, one of pointer, key, or none
• id: String, a unique id chosen to represent this input source for this and future actions
• parameters: pointer-type input sources can also have a parameters property, which is an object with a pointerType key specifying either mouse, pen, or touch. If parameters is omitted, the pointerType is considered to be mouse.
• actions: a list of action objects for this particular input source. An action object has different fields based on the kind of input device it belongs to (see also here)
