You should see a list of different manga
available (these are the manga that are hosted on the Annotation
server that you are using - probably fugu.cs.columbia.edu).
Scroll down until you can see "GMAO Test", select that, and open it.
It should load up the XML file. You are now ready to start creating
bubbles and putting translations in them! On the left hand side of
the screen, open up the tree display so you can see what has been
translated already.
In my case, up to page 6 has been translated. Click on the page folder to load that page up. We want to add a new page. So go to the GMAO->New Page menu item, and enter the next page.
You have to make sure that the file name it suggests is the correct name, or you might get a 404 File Not Found error. Generally, it suggests the correct name. You will have to expand the left hand side again to see the new page. Click on the blank "Page 7" icon to load up the new page.
The Z and X keys can be used to
cycle between the bubble drawing tools on the toolbar. You can also
use tab and space bar to select a button highlighted with tab.
Once you have drawn your bubble, you can add a translation to it by
selected "New Translation" from the GMAO menu. The new translation
will be added to the last bubble the mouse was over. When you have
finished, you should save the file locally (File->Save) or send it to
the server if you are saving changes on the server. You can try that
with the GMAO->Send Page to Server command.
This other tutorial that I wrote up earlier shows a few more features
of GMAO.
