ctrl sequences are SYMBOL & 0x1F

apparently micromite basic translates some ansi sequences to their weird codes, so this may work

                        SHIFT-F3    esc [ 2 5 ~         used in the editor

[MightyPork]

in conclusion it appears the esc [ num ~ codes and Ctrl- codes will be sufficient

implemented client-side, but will need adjustments wrt #52
