  This paper describes the new QuickFind method in LcTools for finding signals
and associated TTVs (Transit Timing Variations) in light curves from NASA space
missions. QuickFind is adept at finding medium to large sized signals
(generally those with S/N ratios above 15) extremely fast, significantly
reducing overall processing time for a light curve as compared to the BLS
detection method. For example, on the lead author's computer, QuickFind was
able to detect both KOI signals for star 10937029 in a 14 quarter Kepler light
curve spanning 1,459 days in roughly 2 seconds whereas BLS took about 155
seconds to find both signals making QuickFind in this example about 77 times
faster than BLS. This paper focuses on the user interfaces, data processing
algorithm, and performance tests for the QuickFind method in LcTools.
