I have got used to control-[ for escape on the iPad Pro keyboard. I use Prompt for SSH (I am used to it, should probably try other options) and I find opening Emacs and using control-x 3 to split the screen vertically works well. I then esc-shell in one window and edit in the other, or just have two files open for editing. If you have a high resolution USB-C interfaced monitor, plugging in the iPad Pro works fine also, but is I am in my home office I just use my laptop. A big external monitor is great though for watching HBO Now, Netflicks, and Prime.
