You can remove a column from the index by selecting the column and clicking the - (minus) button to drop the column from the index.
To change an index to only refer to a column prefix (such as with the CHAR and VARCHAR string data types), select the index column you wish to prefix in the Index Columns box and then click the arrow icon to the right of the Index Columns box. Select the Set Index Column Length option from the drop-down menu that appears. You can set the desired prefix length in the dialog that appears.
