    \class QKeySequence
    \brief The QKeySequence class encapsulates a key sequence as used
    by shortcuts.

    \ingroup shared


    In its most common form, a key sequence describes a combination of
    keys that must be used together to perform some action. Key sequences
    are used with QAction objects to specify which keyboard shortcuts can
    be used to trigger actions.

    Key sequences can be constructed for use as keyboard shortcuts in
    three different ways:

    \list
    \o For standard shortcuts, a \l{QKeySequence::StandardKey}{standard key}
       can be used to request the platform-specific key sequence associated
       with each shortcut.
    \o For custom shortcuts, human-readable strings such as "Ctrl+X" can
       be used, and these can be translated into the appropriate shortcuts
       for users of different languages. Translations are made in the
       "QShortcut" context.
    \o For hard-coded shortcuts, integer key codes can be specified with
       a combination of values defined by the Qt::Key and Qt::Modifier enum
       values. Each key code consists of a single Qt::Key value and zero or
       more modifiers, such as Qt::SHIFT, Qt::CTRL, Qt::ALT and Qt::META.
    \endlist

    For example, \gui{Ctrl P} might be a sequence used as a shortcut for
    printing a document, and can be specified in any of the following
    ways:

    \snippet doc/src/snippets/code/src_gui_kernel_qkeysequence.cpp 0

    Note that, for letters, the case used in the specification string
    does not matter. In the above examples, the user does not need to
    hold down the \key{Shift} key to activate a shortcut specified
    with "Ctrl+P". However, for other keys, the use of \key{Shift} as
    an unspecified extra modifier key can lead to confusion for users
    of an application whose keyboards have different layouts to those
    used by the developers. See the \l{Keyboard Layout Issues} section
    below for more details.

    It is preferable to use standard shortcuts where possible.
    When creating key sequences for non-standard shortcuts, you should use
    human-readable strings in preference to hard-coded integer values.

    QKeySequence objects can be cast to a QString to obtain a human-readable
    translated version of the sequence. Similarly, the toString() function
    produces human-readable strings for use in menus. On Mac OS X, the
    appropriate symbols are used to describe keyboard shortcuts using special
    keys on the Macintosh keyboard.

    An alternative way to specify hard-coded key codes is to use the Unicode
    code point of the character; for example, 'A' gives the same key sequence
    as Qt::Key_A.

    \bold{Note:} On Mac OS X, references to "Ctrl", Qt::CTRL, Qt::Control
    and Qt::ControlModifier correspond to the \key Command keys on the
    Macintosh keyboard, and references to "Meta", Qt::META, Qt::Meta and
    Qt::MetaModifier correspond to the \key Control keys. Developers on
    Mac OS X can use the same shortcut descriptions across all platforms,
    and their applications will automatically work as expected on Mac OS X.

    \section1 Standard Shortcuts

    QKeySequence defines many \l{QKeySequence::StandardKey} {standard
    keyboard shortcuts} to reduce the amount of effort required when
    setting up actions in a typical application. The table below shows
    some common key sequences that are often used for these standard
    shortcuts by applications on four widely-used platforms.  Note
    that on Mac OS X, the \key Ctrl value corresponds to the \key
    Command keys on the Macintosh keyboard, and the \key Meta value
    corresponds to the \key Control keys.

    Note that, since the key sequences used for the standard shortcuts differ
    between platforms, you still need to test your shortcuts on each platform
    to ensure that you do not unintentionally assign the same key sequence to
    many actions.

    \section1 Keyboard Layout Issues

    Many key sequence specifications are chosen by developers based on the
    layout of certain types of keyboard, rather than choosing keys that
    represent the first letter of an action's name, such as \key{Ctrl S}
    ("Ctrl+S") or \key{Ctrl C} ("Ctrl+C").
    Additionally, because certain symbols can only be entered with the
    help of modifier keys on certain keyboard layouts, key sequences intended
    for use with one keyboard layout may map to a different key, map to no
    keys at all, or require an additional modifier key to be used on
    different keyboard layouts.

    For example, the shortcuts, \key{Ctrl plus} and \key{Ctrl minus}, are often
    used as shortcuts for zoom operations in graphics applications, and these
    may be specified as "Ctrl++" and "Ctrl+-" respectively. However, the way
    these shortcuts are specified and interpreted depends on the keyboard layout.
    Users of Norwegian keyboards will note that the \key{+} and \key{-} keys
    are not adjacent on the keyboard, but will still be able to activate both
    shortcuts without needing to press the \key{Shift} key. However, users
    with British keyboards will need to hold down the \key{Shift} key
    to enter the \key{+} symbol, making the shortcut effectively the same as
    "Ctrl+Shift+=".

    Although some developers might resort to fully specifying all the modifiers
    they use on their keyboards to activate a shortcut, this will also result
    in unexpected behavior for users of different keyboard layouts.

    For example, a developer using a British keyboard may decide to specify
    "Ctrl+Shift+=" as the key sequence in order to create a shortcut that
    coincidentally behaves in the same way as \key{Ctrl plus}. However, the
    \key{=} key needs to be accessed using the \key{Shift} key on Norwegian
    keyboard, making the required shortcut effectively \key{Ctrl Shift Shift =}
    (an impossible key combination).

    As a result, both human-readable strings and hard-coded key codes
    can both be problematic to use when specifying a key sequence that
    can be used on a variety of different keyboard layouts. Only the
    use of \l{QKeySequence::StandardKey} {standard shortcuts}
    guarantees that the user will be able to use the shortcuts that
    the developer intended.

    Despite this, we can address this issue by ensuring that human-readable
    strings are used, making it possible for translations of key sequences to
    be made for users of different languages. This approach will be successful
    for users whose keyboards have the most typical layout for the language
    they are using.

    \section1 GNU Emacs Style Key Sequences

    Key sequences similar to those used in \l{GNU Emacs}, allowing up to four
    key codes, can be created by using the multiple argument constructor,
    or by passing a human-readable string of comma-separated key sequences.

    For example, the key sequence, \key{Ctrl X} followed by \key{Ctrl C}, can
    be specified using either of the following ways:

    \snippet doc/src/snippets/code/src_gui_kernel_qkeysequence.cpp 1

    \warning A QApplication instance must have been constructed before a
             QKeySequence is created; otherwise, your application may crash.

    \sa QShortcut
*/

/*!
    \enum QKeySequence::SequenceMatch

    \value NoMatch The key sequences are different; not even partially
    matching.
    \value PartialMatch The key sequences match partially, but are not
    the same.
    \value ExactMatch The key sequences are the same.
    \omitvalue Identical
*/

/*!
    \enum QKeySequence::SequenceFormat

    \value NativeText The key sequence as a platform specific string.
    This means that it will be shown translated and on the Mac it will
    resemble a key sequence from the menu bar. This enum is best used when you
    want to display the string to the user.

    \value PortableText The key sequence is given in a "portable" format,
    suitable for reading and writing to a file. In many cases, it will look
    similar to the native text on Windows and X11.
