map key for ESC

When using the iPadOS client, there needs to be an option to remap keys on the Folio or Magic Keyboard to send a genuine [Esc] key. ctrl+[ works in some scenarios, cmd+. works in others but both of those are unwieldy... being able to map something like the caps lock or ctrl+` would be easier to use

Would be good to have options that are valid for all connections, but also have connection specific overrides
