I have iPhone 15 Pro and would like to add to it portable keyboard for text typing. IMO, it should be bluetooth keyboard and be some kind foldable. Probably it also should have phone stand and it would be nice to have touch pad for fast cursor navigation.

The idea is to have the keyboard always with me (as my iPhone) and use it if I have time during traveling for novel writing.

What are good options (as there is no any original Apple keyboards for iPhones)? What can you suggest?
