These options allow you to skip one bitplane worth of graphics data. This is useful for blitter objects (bobs) where the game will often store the data in Amiga ACBM format with an extra bitplane used as a mask:

Q/AAdjust bitplane width by 8/16 pixels
Q/A + ShiftDouble or half the bitplane width
W/SAdjust bitplane height by 1 pixel
W/S + ShiftAdjust bitplane height by 8 pixels
E/DAdjust number of bitplanes (double/half the number of colours)
R/FAdjust the number of bytes to skip between bitplanes or tiles by 2
R/F + ShiftAdjust the number of bytes to skip between bitplanes or tiles by 16
T/GAdjust the destination ripping width by 16 pixels
T/G + ShiftDouble or half the destination ripping width
Y/HAdjust the destination ripping height by 1 pixel
Y/H + ShiftDouble or half the destination ripping height
U/JAdjust the Y co-ordinate stopping position by 1 pixel
U/J + ShiftAdjust the Y co-ordinate stopping position by 8 pixels
MChange the ripping mode used to convert memory into graphics
Arrow Left/RightMove picture left/right by 2 bytes
Arrow Left/Right + ShiftMove picture left/right by 1 tile
Arrow Up/DownMove picture up/down by 1 pixel
Arrow Up/Down + ShiftMove picture up/down by 1 tile
XSet Skip Mode (B = Bitplanes, T = Tiles)
1-8Increase the bitplane assigned
1-8 + ShiftDecrease the bitplane assigned
