- big welcome to the forum.
Please go to the KWiin > All Effects
page and making sure the Zoom option is is enabled go to the right hand side off the Zoom line you should see an icon with a spanner on it.
Click on the spanner icon and it should see the image below
Now select one of the shortcuts and it should show two fields - Default
and the other is Custom
If the Default
isn't to your liking choose the Custom
With the Custom
one enabled click on the button that says None
and you can now enter your own choice of shortcut keys
When done, press the OK button and hopefully it will work for you
