 ## Scan Types
 
 You can use the following scan types.
 
-- **next** : It scans sequentially from the first HEX value to the last HEX value.
-- **prev** : It scans in reverse order from the last HEX value to the first HEX value.
-- **random** : It scans by generating completely random HEX values. The generated HEX values are derived from the HEX ranges of the entered Puzzle.
+- **SB** : It scans sequentially from the beginning HEX value to the last HEX value; first to last.
+- **SE** : It scans in reverse order from the end HEX value to the beginning HEX value; last to first.
+- **R** : It scans by generating completely random HEX values. The generated HEX values are derived from the HEX ranges of the entered Puzzle.
