Is it possible to enable key repeat for letter keys on the Apple Smart Keyboard for iPad Pro? The key repeat options in iOS Keyboard settings seem to work for the navigation keys (arrows, backspace, etc) but not for the letter keys. When I hold down a letter key, it does not repeat. Is it possible to change this behavior to allow all keys to repeat like on a regular desktop keyboard?
As far as I can tell this isn't possible, which is a shame. I was trying to use my iPad with remote desktop where I need to hold down keys and it just doesn't work. It seems this is a "feature" of iOS that only certain keys like space and delete are allowed to repeat. Here are some links about it that I found.
