Is there a forward delete on the iPad? Using the screen keyboard on iPad, is their a way to delete the character after the cursor?  That is, behavior like the Windows delete key?  

I am aware that the convention is to use Fn+delete on Macs.  If there is no such convention on iPad, it might be nice to use shift+delete.
Sorry, but no.  This only works on the iPad if you are using an external Bluetooth keyboard.
