Clear or delete text over ECP

Is there a way you can hit the “clear” or “delete” (backspace) buttons by sending some command over external control, like how you can enter text with /keypress/Lit_a (etc) and submit it with /keypress/Enter? There doesn’t seem to be a /keypress/Clear or anything like that, and sending /keypress/%08 (Unicode 0x0008 = backspace) doesn’t work either.

No “clear” that I’m aware of, but “Backspace” is a valid key… /keypress/Backspace
