Frequ mode ?s-lost mouse over freq nos.

Hi - A Schope newb here

What does the right hand figure of the two nos above each channel offset knob represent?
I presume the left hand no. is scrubbing through the period of time from the freeze moment?
Is 500ms the max time?

Also mousing over Freq spectrum graph gave v useful read out stats which have since disappeared???
