/**
* 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 "<Control>a" or "<Shift><Alt>F1" or
* "<Release>z" (the last one is for key release). The parser
* is fairly liberal and allows lower or upper case, and also
* abbreviations such as "<Ctl>" and "<Ctrl>".
*
* 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.

* Converts an accelerator keyval and modifier mask
* into a string parseable by egg_accelerator_parse_virtual().
* For example, if you pass in #GDK_q and #EGG_VIRTUAL_CONTROL_MASK,
* this function returns "<Control>q".
*
* The caller of this function must free the returned string.
