Can you use a Bluetooth mouse or the Magic Mouse 2 with the iPad Pro?

No iDevice can use an external mouse or trackpad device.

No pointing cursor to move on screen.

That stated you can move around the text "I" beam insertion point cursor by bringing up the iPad's software keyboard, do a two finger single tap to turn the entire keyboard area gray colored and into a gigantic trackpad area where you can easily control the position of the text insertion point "I" beam cursor.

You can highlight text and lines of text by doing a two finger double tap on the iOS software keyboard.

Then, do a single two finger tap on the keyboard area to fine tune the text selection.

That is as close to a mouse or regular trackpad that iOS is, currently, going to get.

Good Luck
