Action

An action is a change in the game interface as a result of mouse and/or keyboard input. Actions are partitioned into the following categories.

Command
Commands are actions that have an effect on the game units. Example commands are: move, burrow, build SCV, feedback. Actions that are not commands are called operations, although in this wiki we will never talk about operations in general and we will typically refer to operations of some specific kind.

Command operation
Many command can only be issued by executing a sequence of actions, such as pressing the command button and then selecting a target. Those commands are called mediated, whereas all the other commands are called immediate. For example, Stimpack is an immediate command, while Fungal Growth is a mediated command. Actions that are necessary to issue a command, but that do not have an immediate effect on the game are called command operations.

Selection operation
Selection operations are actions that modify the current selection or the current focused group or the selection stored inside control groups. Example selection operations are box-select, select control group, previous subgroup, select larva. Control group operations also belong to this group.

Camera operation
Camera operations are actions that modify the information currently displayed on-screen. Example camera actions are mouse-scroll, keyboard scroll, center on camera location, base camera, center current selection, display enemy units' health bars, rotate camera.

UI operation
UI operations are operations that modify the user interface, such as show team colors, show minimap terrain, and all the other options typically accessible via menu.

Team actions
Team actions are, for example: minimap ping, send minerals, send gas.
