# helpKey Properties File Names

Names of helpKey properties files are arbitrary (as long as they end with .properties). However, a context-sensitive help plug-in could contribute pairs of helpKey properties files for several UI plug-ins, and the files would need to have unique names, if they were located in the same directory.

As a convention, helpKey properties file names should correspond with the UI plug-in that they serve. For example:

- org.eclipse.datatools.connectivity.ui.contextIds.properties
- org.eclipse.datatools.connectivity.ui.searchExpressions.properties

To allow arbitrary names for helpKey properties files, and to abstract the names of helpKey properties files from UI components, the DTP help-helper provides an extension point (org.eclipse.datatools.help.helpKeyProperties). That extension point allows any plug-in to declare helpKey properties file contributions for a UI plug-in.
