+    \class TQKeySequence qkeysequence.h
+    \brief The TQKeySequence class encapsulates a key sequence as used
+    by accelerators.
+
+    \ingroup misc
+
+    A key sequence consists of up to four keyboard codes, each
+    optionally combined with modifiers, e.g. \c SHIFT, \c CTRL, \c
+    ALT, \c META, or \c UNICODE_ACCEL. For example, \c{CTRL + Key_P}
+    might be a sequence used as a shortcut for printing a document.
+    The key codes are listed in \c{qnamespace.h}. As an alternative,
+    use \c UNICODE_ACCEL with the unicode code point of the character.
+    For example, \c{UNICODE_ACCEL + 'A'} gives the same key sequence
+    as \c Key_A.
+
+    Key sequences can be constructed either from an integer key code,
+    or from a human readable translatable string such as
+    "Ctrl+X,Alt+Space". A key sequence can be cast to a TQString to
+    obtain a human readable translated version of the sequence.
+    Translations are done in the "TQAccel" context.
