The codes from $01 to $0F are control characters. These values are associated with cursor control characters, which will move the cursor. The code $05 sets the cursor to its home position. The home position is at the first line at its first column normally. The code $06 clears the screen. Both characters can be displayed if you use a Basic.

$0D sets the cursor to the first column of the next line. DEL deletes the last character before the actual cursor position. INS means insert a character at the cursor position. SP spaces 1 character.

GR invokes the function of the GRPH key. Using the GRPH key will display the graphic patterns shown at the front side of the keys.

The characters from $A0 to $FE are displayed inverted.
