Close - but not really "continuous tuning" like an analog tuned receiver.

For New Digital types like your R75 -- the VFO tuning is in selectable
discrete steps i.e.,
from as low as 1 Hertz -- up to 100 kHz see -- page 12 and 13 of the ICOM
Manual. Also a 1 MHz "Quick Tuning" increment can be used for fast tuning.

And many mil and commercial rigs -- use the term VFO - so not an exclusive
Ham term per se

The instruction manual that comes with my brand new R75 talks about
memory and VFO. I understand memory, but what is VFO?

This is just the ham-radio heritage of ICOM showing through. VFO is ham
jargon, its the acronym for Variable Frequency Oscillator. Here, it means
the same thing as Continuous Tuning. On the R75, the difference between
memory & VFO modes becomes most important when you punch the SCAN button.
In VFO mode, the frequency starts changing continuously, as if some
internal motor were turning the tuning knob. Push SCAN in Memory mode,
and the R75 starts jumping through the preset channels without covering
any frequencies "between".
