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:
“The principal office of history I take to be this: to prevent virtuous actions from being forgotten, and that evil words and deeds should fear an infamous reputation with posterity.”
—Tacitus (c. 55–c. 120)
“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)
“There is a Book
By seraphs writ with beams of heavenly light,
On which the eyes of God not rarely look,
A chronicle of actions just and bright—
There all thy deeds, my faithful Mary, shine;
And since thou own’st that praise, I spare thee mine.”
—William Cowper (1731–1800)
