InstallMate sets this variable to a nonzero value if the currently active feature (in the active OptionTree control) is browsable, or to 0 if not. This variable is used to enable or disable feature-based folder browsing in the installer's user interface. You can control feature-based folder browsing through the Allow folder browsing attribute of each feature.
You can refer to this variable as <TsuFeatureBrowsable>. In conditional expressions you can omit the brackets and simply use TsuFeatureBrowsable as a test. Do not change its value; it is set and updated automatically by InstallMate.
