  Rapid Blue- and Red-shifted Excursions (RBEs and RREs) are likely to be the
on-disk counterparts of Type II spicules. Recently, heating signatures from
RBEs/RREs have been detected in IRIS slit-jaw images dominated by
transition-region lines around network patches. Additionally, signatures of
Type II spicules have been observed in AIA diagnostics. The full-disk,
ever-present nature of the AIA diagnostics should provide us with sufficient
statistics to directly determine how important RBEs and RREs are to the heating
of the transition region and corona. We find, with high statistical
significance, that at least 11% of the low-coronal brightenings detected in a
quiet-Sun region in 304, can be attributed to either RBEs or RREs as observed
in H\alpha, and a 6% match of 171 detected events to RBEs or RREs with very
similar statistics for both types of H\alpha\ features. We took a statistical
approach that allows for noisy detections in the coronal channels and provides
us with a lower, but statistical significant, bound. Further, we consider
matches based on overlapping features in both time and space, and find strong
visual indications of further correspondence between coronal events and
co-evolving but non-overlapping, RBEs and RREs.
