| :sl:`pygame module to work with the keyboard`

This module contains functions for dealing with the keyboard.

The event queue gets ``pygame.KEYDOWN`` and ``pygame.KEYUP`` events when the
keyboard buttons are pressed and released. Both events have a key attribute
that is a integer id representing every key on the keyboard.

The ``pygame.KEYDOWN`` event has an additional attributes unicode, and
scancode. unicode represents a single character string that is the fully
translated character entered. This takes into account the shift and composition
keys. scancode represents the platform specific key code. This could be
different from keyboard to keyboard, but is useful for key selection of weird
keys like the multimedia keys.

There are many keyboard constants, they are used to represent keys on the
keyboard. The following is a list of all keyboard constants

The keyboard also has a list of modifier states that can be assembled bit
bitwise ORing them together.



.. function:: get_focused

   | :sl:`true if the display is receiving keyboard input from the system`
   | :sg:`get_focused() -> bool`

   This is true when the display window has keyboard focus from the system. If
   the display needs to ensure it does not lose keyboard focus, it can use
   ``pygame.event.set_grab()`` to grab all input.

   .. ## pygame.key.get_focused ##

.. function:: get_pressed

   | :sl:`get the state of all keyboard buttons`
   | :sg:`get_pressed() -> bools`

   Returns a sequence of boolean values representing the state of every key on
   the keyboard. Use the key constant values to index the array. A True value
   means the that button is pressed.

   Getting the list of pushed buttons with this function is not the proper way
   to handle text entry from the user. You have no way to know the order of
   keys pressed, and rapidly pushed keys can be completely unnoticed between
   two calls to ``pygame.key.get_pressed()``. There is also no way to translate
   these pushed keys into a fully translated character value. See the
   ``pygame.KEYDOWN`` events on the event queue for this functionality.

   .. ## pygame.key.get_pressed ##

.. function:: get_mods

   | :sl:`determine which modifier keys are being held`
   | :sg:`get_mods() -> int`

   Returns a single integer representing a bitmask of all the modifier keys
   being held. Using bitwise operators you can test if specific shift keys are
   pressed, the state of the capslock button, and more.

   .. ## pygame.key.get_mods ##

.. function:: set_mods

   | :sl:`temporarily set which modifier keys are pressed`
   | :sg:`set_mods(int) -> None`

   Create a bitmask of the modifier constants you want to impose on your

   .. ## pygame.key.set_mods ##

.. function:: set_repeat

   | :sl:`control how held keys are repeated`
   | :sg:`set_repeat() -> None`
   | :sg:`set_repeat(delay, interval) -> None`

   When the keyboard repeat is enabled, keys that are held down will generate
   multiple ``pygame.KEYDOWN`` events. The delay is the number of milliseconds
   before the first repeated ``pygame.KEYDOWN`` will be sent. After that
   another ``pygame.KEYDOWN`` will be sent every interval milliseconds. If no
   arguments are passed the key repeat is disabled.

   When pygame is initialized the key repeat is disabled.

   .. ## pygame.key.set_repeat ##

.. function:: get_repeat

   | :sl:`see how held keys are repeated`
   | :sg:`get_repeat() -> (delay, interval)`

   When the keyboard repeat is enabled, keys that are held down will generate
   multiple ``pygame.KEYDOWN`` events. The delay is the number of milliseconds
   before the first repeated ``pygame.KEYDOWN`` will be sent. After that
   another ``pygame.KEYDOWN`` will be sent every interval milliseconds.

   When pygame is initialized the key repeat is disabled.

   New in pygame 1.8.

   .. ## pygame.key.get_repeat ##

.. function:: name

   | :sl:`get the name of a key identifier`
   | :sg:`name(key) -> string`

   Get the descriptive name of the button from a keyboard button id constant.

   .. ## pygame.key.name ##

.. ## pygame.key ##
