Description—Specifies the description to display in the Context Help window when you move the cursor over the item in the Project Explorer window. You can format the text in Description to appear bold in the Context Help window.
Help path—Contains the path or symbolic path to the HTML file or to the compiled help file you want to link to from the Context Help window. If this field is empty, the blue Detailed help link does not appear in the Context Help window, and the Detailed help button is dimmed. You also can use the Help:Document Path property to set the help path programmatically.
Note If you do not provide a Detailed help link for a dynamic child member VI in a LabVIEW class or interface, LabVIEW displays the Detailed help link for the nearest ancestor class dynamic member VI of the same name, if available.
Help tag—Contains the HTML filename or index keyword of the topic you want to link to in a compiled help file (.chm or .hlp). To link to a bookmark within an HTML file, add # followed by the name of the bookmark to the end of the filename. You also can use the Help:Document Tag property to set the help tag programmatically.
