Keep the time
Tap a beat to cycle accent → normal → silent
Nudges the tempo up every few bars so you can build speed without noticing the climb.
Drops the click for a few bars and brings it back, so you find out whether your internal clock actually holds. The bar count keeps running while it is silent.
