* Parses a string representing a virtual accelerator. The format

|

*
|
||||
* 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.
