Adding TPL after JSP in Wordfile.txt at language 3 should do the job. If it is not functioning, as you described, you are not using this wordfile or the file as an other extension than tpl. Check both.
In UltraEdit open Advanced - Configuration - Syntax Highlighting
and look for the name and path of the wordfile. Open the wordfile and check again that TPL is added to the HTML language.
In Windows Explorer open the folder options and disable "Hide file extensions for known file types" to see the real file extension.
In UE v15.00 and later adding the file extension TPL to the list of file extensions for being highlighted with HTML must be done as follows:
- Open Advanced - Configuration - Editor Display - Syntax Highlighting.
- Select language HTML if not already preselected.
- Press the button Open to the right of the language.
- Close the configuration dialog with button Cancel.
- The wordfile html.uew used for syntax highlighting HTML files (with other languages inside) is open now. Move caret to end of first line with the list of file extensions.
- Add the file extension TPL (case does not matter on Windows).
- Save the wordfile and close it.
Next time a file with extension TPL is opened, it will be automatically highlighted as HTML file. Already opened TPL files may need to be reloaded using File - Revert to Saved
