Changes the accel_key and accel_mods currently associated with accel_path. Due to conflicts with other accelerators, a change may not always be possible, replace indicates whether other accelerators may be deleted to resolve such conflicts. A change will only occur if all conflicts could be resolved (which might not be the case if conflicting accelerators are locked). Successful changes are indicated by a TRUE return value.
Note that accel_path string will be stored in a GQuark Therefore, if you pass a static string, you can save some memory by interning it first with g_intern_static_string().

TRUE if other accelerators may be deleted upon conflicts
