Thanks for your help, but your solution makes it harder, I'm willing to hold down the CTRL key until I hold down the middle mouse button and rotate it, probably a month later the middle mouse button will crash, something You say that I should use B instead of A. I just wanted to find a way to replace CTRL with ALT

Hi I used Illustrator software for many years, but due to multiple crashes and heaviness in new versions (it was very difficult for me) so I decided to use Affinity Designer, because it is very light and smooth (even for computers with low processing and low graphics) but unfortunately one of the problems is here, in Illustrator I kept the "Alt" key to zoom in and out by rotating the middle mouse button to make the image smaller and larger Unfortunately in this software I have to hold down the "Ctrl" key to do this, please help me how I can change this feature and replace the "Alt" and "Ctrl" keys to zoom in and out This is very bad for my nerves because for years I used software that I used to zoom by holding down the Alt key.
