*@SPI_KEYLISTENER_ALL_WINDOWS: Events are received not from the application toolkit layer, but
* from the device driver or windowing system subsystem; such notifications are 'global' in the
* sense that they are not broken or defeated by applications that participate poorly
* in the accessibility APIs, or not at all; however because of the intrusive nature of
* such snooping, it can have side-effects on certain older platforms. If unconditional

* a commonly used combination which gives the AT complete control over the delivery of matching
* events. However, such filters should be used sparingly as they may have a negative impact on
