It's important to save frequently while you work on your project. The
program also saves the project when you close it.
To save a project:
Click SaveAll or press CTRL+S.
Tips:
You can
save individual parts of your project as you are using various features
in the program. The File menu includes
a Save [item]
feature that saves individual files in your project. For example,
if you make changes to your index, the Save menu option is “Save Index”
while the Index Designer is open.
The General tab at the Options dialog (accessed
from the Tools menu) includes a
feature called "Save without prompt". This feature is on by default
so any changes you make to a topic are automatically saved when you close
the topic and open another one in the WYSIWYG or TrueCode Editor. If you
do not want the program to automatically save your edits, you can deselect
this feature.
