RoboHelp 9 provides a program to test the context sensitivity of your WebHelp projects. This CSH tester is located in the Tools pod.

Unfortunately, the CSH tester only supports testing map numbers. For this reason my custom WebHelp APIs contain example programs to test the context sensitivity. If you are looking for a simple program to test the context sensitivity of your projects, download the C# CSH tester. Unzip the executable and the pdf files. Run the program and enjoy.

If you are looking for APIs for other languages, check the page WebHelp APIs. If you want to know all the ins and outs of context sensitivity in WebHelp, see Context Sensitivity in WebHelp.
