Buon giorno parduz, benvenuto to the forum.
You have mixed up something. %word%.html is of course no valid file name. Go to "Settings > Highlighter Settings..." Choose left HTML and right "Specification" and put there by HELP FILE the path to your help.CHM file in. Now, if you press ALT+F1 in an HTML document your HTML-Help.chm will open. If you stand on an word in your document then this word is searched and shown in the help. Right now i don't remember if other types then CHM are supported , just try it. -- you could also use the ToolPanel on the left side of PSPad. There you can add to the favorites an Tool. Put there e.g. the path to your HTML-Help.chm in and THERE you can use this %word% placeholder.
