Touchportal is the way to go - works on any platform. Unlimited buttons, macros, preset pages for different uses, including a Zoom call or PowerPoint, or Photoshop.

You pay once - for iPad, as far as I remember, long time ago was something like $12.

I couldn't do my job (translating) without it on the many platforms I need to use, each with their own shortcuts.

Actually, a dry microfiber cloth is enough to dust all surfaces, not just electronics. Dampening it will smear the dust and create a dirty film instead of cleaning. That's what I'm doing after also researching the topic a lot.
