+ This string may be either in the same format as returned by
+ ToString(), i.e. contain the accelerator itself only, or have the
+ format of a full menu item text with i.e. <code>Label TAB
+ Accelerator</code>. In the latter case, the part of the string
+ before the TAB is ignored. Notice that the latter format is only
+ supported for the compatibility with the previous wxWidgets
+ versions and the new code should pass only the accelerator string
+ itself to this function.
