A new feature has been added to Cinelerra-GG that lets you get Help on a specific item while running the program.
Help can be requested by pointing with the mouse cursor on the GUI element of interest and pressing Alt/h.
The most relevant referenced section of the HTML manual will appear in a tab of your configured browser. Specific items of Help include windows, menus, tooltips, icons, buttons, plugins, transitions, and more. Detailed usage can be seen here.
Note to people who do their own builds. To include the Context Help you will need to download the HTML manual here and
unpack to your Cinelerra/bin/doc directory.
