Styles continuing from previous or using a key command

The key command mappings I set up on my Mac for the project I am working on don’t seem to apply when I use iOS Scrivener for the same projects. e.g. opt-cmd-8 activates a certain style on Mac, has no effects when using iOS.

Also, on the Mac, I have the styles set up to not select a “next” style, so when I hit enter, it keeps using that style,. On iOS it defaults to the non-style text.And, because I cant use the key comments, I have to take my hands off the keyboard to use the mouse to select the right style. It doesn’t sound huge, but when I have to do this for every paragraph it gets a little frustrating.

Is there any way to correct this behavior on iOS ?
