» Hover Help Plug-in Guide # Hover Help Set Up This section describes the initial set up of Hover Help and how to add a Developer Library plug-in. ## Developer Library Indexing When the Carbide IDE starts, Hover Help automatically prepares for its first use by indexing its Developer Library. This process takes a few seconds, and progress is displayed in the Progress view. If you cancel indexing from the Progress view, Hover Help will be deactivated. You can reactivate Hover Help using the preferences panel, and the indexing will start again. ## Adding a New Developer Library Plug-in New versions of the Developer Library plug-in are published regularly. You can configure Hover Help to use a new version as follows: Obtain the latest Developer Library plug-in from the Forum Nokia > Symbian/C++ Documentation website, and copy the new plug-in into Carbide’s `plugins` directory. NOTE If you experience problems connecting to the site, verify that the connection settings are correct in the Network Connections preference panel before trying again. This is especially important if a proxy setting is required to connect to the internet. Restart Carbide. From the Window > Preferences > Carbide.c++ > Hover Help preferences panel, make sure the added Developer Library is selected. If not, select it from the Developer Libraries drop-down box. ## Activating Hover Help If Hover Help is deactivated, you can activate it from the Window > Preferences > Carbide.c++ > Hover Help preferences panel by unchecking the "Deactivate Hovering" option. When you activate Hover Help, the checkbox "Automatically select latest Developer Library" is automatically checked. If you need a particular Developer Library, uncheck the checkbox "Automatically select latest Developer Library". Then select a Developer Library from the Developer Libraries drop-down box.
