Activate and adjust the frequency of the low cut and high cut filter command?

Hi,
Do you know if there is any shortcut or key command that allows to turn on and adjust the frequency of the low cut and high cut filters in the pre section of the channel settings in Cubase? I mean not having to turn on the filter and then adjust the frequency, but the filter is activated with some combination by clicking on the knob/fader that controls the frequency. I’ve seen a tutorial where they seem to do it, with Cubase v. 9.5, on Mac. I use Windows, but I guess that shouldn’t matter.
Thanks in advance.
Cheers.
