The new iPad Magic Keyboard does not have an Escape key. This might cause issues if you're hoping to use Vim, or another CLI tool which uses that key. I'm not sure if you can remap any other keys (like Caps Lock) to function as Escape on iPadOS.
Ctrl+[ can be used as Esc in a pinch.
For vim, I'd recommend mapping 'fd' or 'kj' to Esc.
inoremap fd <Esc>
Update: Blink allows remapping Caps Lock to Esc :)
Argh, that is a supreme bummer (and honestly not that surprising). I wonder if some of the custom keymapping functionality in iPadOS 13.4 could help?
