+ * "&lt;Release&gt;z" (the last one is for key release). The parser

+ * is fairly liberal and allows lower or upper case, and also

+ *

+ * If the parse fails, @accelerator_key and @accelerator_mods will

+ * 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.
