How to zoom FFT display

[Lee3]

How do I zoom the FFT display in Affinity Photo Windows version. All the help says is hold down the Alt key??? Nothing I have tried zooms the FFT display. Help

Hi,

 

in the AP Win try version with a german keyboard layout, the right side Alt-key (which is labeled Alt-Gr on a german kb) + mouse scrollwheel did the zooming in/out job! - Using the left side Alt-key of the keyboard didn't do anything during my tryouts here.

 

You can also assign another key here under the AP keyboard settings section for FFT.

On US windows version it is Ctrl+Scroll wheel
