All INTERACT Codes and Classes are case sensitive, this means that "A" is handled as a different character than "a".
If different observers have logged basically the same Codes, but used different cases for writing them, INTERACT can help you change the case of all Codes with one command!
▪Click Transform - Codes - All to Lower Case 
, to change ALL Codes into lower case immediately
▪Click Transform - Codes - All to Upper Case 
, to change ALL Codes into UPPER case immediately!
| TIP: | If you want to change the cases used more specifically, you need to use the Rename Codes functionality for each Code separately. Pay attention to the available Ignore case option in the Replace dialog. |
