142	\class QKeySequence
143	\brief The QKeySequence class encapsulates a key sequence as used
144	by shortcuts.
145
146	\ingroup shared
147	\inmodule QtGui
148
149
150	In its most common form, a key sequence describes a combination of
151	keys that must be used together to perform some action. Key sequences
152	are used with QAction objects to specify which keyboard shortcuts can
153	be used to trigger actions.
154
155	Key sequences can be constructed for use as keyboard shortcuts in
156	three different ways:
157
158	\list
159	\li For standard shortcuts, a \l{QKeySequence::StandardKey}{standard key}
160	can be used to request the platform-specific key sequence associated
161	with each shortcut.
162	\li For custom shortcuts, human-readable strings such as "Ctrl+X" can
163	be used, and these can be translated into the appropriate shortcuts
164	for users of different languages. Translations are made in the
165	"QShortcut" context.
166	\li For hard-coded shortcuts, integer key codes can be specified with
167	a combination of values defined by the Qt::Key and Qt::KeyboardModifier
168	enum values. Each key code consists of a single Qt::Key value and zero
169	or more modifiers, such as Qt::ShiftModifier, Qt::ControlModifier,
170	Qt::AltModifier and Qt::MetaModifier.
171	\endlist
172
173	For example, \uicontrol{Ctrl P} might be a sequence used as a shortcut for
174	printing a document, and can be specified in any of the following
175	ways:
176
177	\snippet code/src_gui_kernel_qkeysequence.cpp 0
178
179	Note that, for letters, the case used in the specification string
180	does not matter. In the above examples, the user does not need to
181	hold down the \uicontrol{Shift} key to activate a shortcut specified
182	with "Ctrl+P". However, for other keys, the use of \uicontrol{Shift} as
183	an unspecified extra modifier key can lead to confusion for users
184	of an application whose keyboards have different layouts to those
185	used by the developers. See the \l{Keyboard Layout Issues} section
186	below for more details.
187
188	It is preferable to use standard shortcuts where possible.
189	When creating key sequences for non-standard shortcuts, you should use
190	human-readable strings in preference to hard-coded integer values.
191
192	QKeySequence objects can be cast to a QString to obtain a human-readable
193	translated version of the sequence. Similarly, the toString() function
194	produces human-readable strings for use in menus. On Apple platforms, the
195	appropriate symbols are used to describe keyboard shortcuts using special
196	keys on the Macintosh keyboard.
197
198	An alternative way to specify hard-coded key codes is to use the Unicode
199	code point of the character; for example, 'A' gives the same key sequence
200	as Qt::Key_A.
201
202	\note On Apple platforms, references to "Ctrl", Qt::CTRL, Qt::Key_Control
203	and Qt::ControlModifier correspond to the \uicontrol Command keys on the
204	Macintosh keyboard, and references to "Meta", Qt::META, Qt::Key_Meta and
205	Qt::MetaModifier correspond to the \uicontrol Control keys. In effect,
206	developers can use the same shortcut descriptions across all platforms,
207	and their applications will automatically work as expected on Apple platforms.
208
209	\section1 Standard Shortcuts
210
211	QKeySequence defines many \l{QKeySequence::StandardKey} {standard
212	keyboard shortcuts} to reduce the amount of effort required when
213	setting up actions in a typical application. The table below shows
214	some common key sequences that are often used for these standard
215	shortcuts by applications on four widely-used platforms. Note
216	that on Apple platforms, the \uicontrol Ctrl value corresponds to the \uicontrol
217	Command keys on the Macintosh keyboard, and the \uicontrol Meta value
218	corresponds to the \uicontrol Control keys.

293
294	Note that, since the key sequences used for the standard shortcuts differ
295	between platforms, you still need to test your shortcuts on each platform
296	to ensure that you do not unintentionally assign the same key sequence to
297	many actions.
298
299	\section1 Keyboard Layout Issues
300
301	Many key sequence specifications are chosen by developers based on the
302	layout of certain types of keyboard, rather than choosing keys that
303	represent the first letter of an action's name, such as \uicontrol{Ctrl S}
304	("Ctrl+S") or \uicontrol{Ctrl C} ("Ctrl+C").
305	Additionally, because certain symbols can only be entered with the
306	help of modifier keys on certain keyboard layouts, key sequences intended
307	for use with one keyboard layout may map to a different key, map to no
308	keys at all, or require an additional modifier key to be used on
309	different keyboard layouts.
310
311	For example, the shortcuts, \uicontrol{Ctrl plus} and \uicontrol{Ctrl minus}, are often
312	used as shortcuts for zoom operations in graphics applications, and these
313	may be specified as "Ctrl++" and "Ctrl+-" respectively. However, the way
314	these shortcuts are specified and interpreted depends on the keyboard layout.
315	Users of Norwegian keyboards will note that the \uicontrol{+} and \uicontrol{-} keys
316	are not adjacent on the keyboard, but will still be able to activate both
317	shortcuts without needing to press the \uicontrol{Shift} key. However, users
318	with British keyboards will need to hold down the \uicontrol{Shift} key
319	to enter the \uicontrol{+} symbol, making the shortcut effectively the same as
320	"Ctrl+Shift+=".
321
322	Although some developers might resort to fully specifying all the modifiers
323	they use on their keyboards to activate a shortcut, this will also result
324	in unexpected behavior for users of different keyboard layouts.
325
326	For example, a developer using a British keyboard may decide to specify
327	"Ctrl+Shift+=" as the key sequence in order to create a shortcut that
328	coincidentally behaves in the same way as \uicontrol{Ctrl plus}. However, the
329	\uicontrol{=} key needs to be accessed using the \uicontrol{Shift} key on Norwegian
330	keyboard, making the required shortcut effectively \uicontrol{Ctrl Shift Shift =}
331	(an impossible key combination).
332
333	As a result, both human-readable strings and hard-coded key codes
334	can both be problematic to use when specifying a key sequence that
335	can be used on a variety of different keyboard layouts. Only the
336	use of \l{QKeySequence::StandardKey} {standard shortcuts}
337	guarantees that the user will be able to use the shortcuts that
338	the developer intended.
339
340	Despite this, we can address this issue by ensuring that human-readable
341	strings are used, making it possible for translations of key sequences to
342	be made for users of different languages. This approach will be successful
343	for users whose keyboards have the most typical layout for the language
344	they are using.
345
346	\section1 GNU Emacs Style Key Sequences
347
348	Key sequences similar to those used in \l{http://www.gnu.org/software/emacs/}{GNU Emacs}, allowing up to four
349	key codes, can be created by using the multiple argument constructor,
350	or by passing a human-readable string of comma-separated key sequences.
351
352	For example, the key sequence, \uicontrol{Ctrl X} followed by \uicontrol{Ctrl C}, can
353	be specified using either of the following ways:
354
355	\snippet code/src_gui_kernel_qkeysequence.cpp 1
