The problem is with word pairs as e.g.: @end quotation You need to include words like quotation, titlepage e.t.c. into keywords too It will be available in the next build, include modified highlighter definition -- <http://forum.pspad.com/read.php?2,68507,68637> PSPad freeware editor http://www.pspad.com
