·          In PLSQL-Developer, Tools (menu)-Preferences (item)-User Interface(Section)-Editor(Item)-Syntax Highlighting (section) - Enable (chekced); Keywords (Bold - checked); Keyword Case (Uppercase - selected). Although it is not perfect, I have attached the Beautifier rules that I use to format the code and then clean it up a bit more from there to conform to standards. You can load it by clicking the Edit button in that item and then Load. For example, if there are more than two arguments, they should be on the next line and indented 2 spaces after the PROCEDURE name with the IS on its own line.

      The beautifier rule file is like the following. Save it to aa.br. Load aa.br as the PL/SQL Beautifier.
