This allows for faster scrolling between section links, in file and directory selectors, and in manuals, without repeatedly pressing buttons. The setting's unit is repetitions per second. Its default value is set to 10, and anything between 0 (disabled) and 20 (50 ms) is acceptable. Grabbing &(instance of GMenu2X).confInt["buttonRepeatRate"] is unsafe, because the storage for the slot may move as the slot is deleted or added. Instead, a callback jumps back into the context of an InputManager so the value can be read from a GMenu2X object's configuration. A GMenu2X object is also passed to InputManager::init.
