Actions
XKB allows for associating actions with key presses, which moves some of the burden of input event processing from client applications to the X server. However, the actions that can be associated with keys are limited to the following:
- Change the state of a modifier, making it active, inactive, latched or locked
- Change the state of the group selectors (same as modifiers)
- Simulate a mouse event (movement or button activity)
- Change the active screen (this kind of action is optional, that is, not necessarily supported by the server)
- Change the state of boolean controls
- Generate a message event (that is, a packet that is sent to the client)
- Generate a different keycode
Moreover, there are some actions related to devices that are available if the server supports the X Input extension.

Famous quotes containing the word actions:
“Our actions seem to have their lucky and unlucky stars, to which a great part of that blame and that commendation is due which is given to the actions themselves.”
—François, Duc De La Rochefoucauld (1613–1680)
“As soon as we exceed average human goodness by even a single step, our actions arouse suspicion. Virtue stands steadily “in the middle.””
—Friedrich Nietzsche (1844–1900)
“Long ago I added to the true old adage of “What is everybody’s business is nobody’s business,” another clause which, I think, more than any other principle has served to influence my actions in life. That is, What is nobody’s business is my business.”
—Clara Barton (1821–1912)
