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:
“I also believe that few people remain completely untouched by the thought that instead of the life they lead there might also be another, where all actions proceed from a very personal state of excitement. Where actions have meanings, not just causes. And where a person, to use a trivial word, is happy, and not just nervously tormenting himself.”
—Robert Musil (1880–1942)
“The first glance at History convinces us that the actions of men proceed from their needs, their passions, their characters and talents; and impresses us with the belief that such needs, passions and interests are the sole spring of actions.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“One will seldom go wrong in attributing extreme actions to vanity, moderate ones to habit, and petty ones to fear.”
—Friedrich Nietzsche (1844–1900)
