- * egg_accelerator_parse_virtual:
- * @accelerator: string representing an accelerator
- * @accelerator_key: return location for accelerator keyval
- * @accelerator_mods: return location for accelerator modifier mask
- *
- * Parses a string representing a virtual accelerator. The format
- * looks like "&lt;Control&gt;a" or "&lt;Shift&gt;&lt;Alt&gt;F1" or
- * "&lt;Release&gt;z" (the last one is for key release). The parser
- * is fairly liberal and allows lower or upper case, and also
- * abbreviations such as "&lt;Ctl&gt;" and "&lt;Ctrl&gt;".
- *
- * If the parse fails, @accelerator_key and @accelerator_mods will
- * be set to 0 (zero) and %FALSE will be returned. If the string contains
- * only modifiers, @accelerator_key will be set to 0 but %TRUE will be
- * returned.
- *
- * The virtual vs. concrete accelerator distinction is a relic of
- * how the X Window System works; there are modifiers Mod2-Mod5 that
- * can represent various keyboard keys (numlock, meta, hyper, etc.),
- * the virtual modifier represents the keyboard key, the concrete
- * modifier the actual Mod2-Mod5 bits in the key press event.
- *
- * Returns: %TRUE on success.
