Topic ID Prefix:

Any text you enter here is automatically added as a prefix to the suggested topic ID when you create a new topic. Note that this function can only be used for new topics; you cannot automatically change existing topic IDs.

Help Context Numbers:

If you activate this function help context numbers will be assigned to new topics automatically, starting with the Start with number. Each new number will be generated by incrementing the last number assigned by the Increment by setting.

This function will only be used for new topics and anchors created after it is activated. You can add, delete and change the context numbers of existing topics with the Help Context Tool.

Apply help context numbers to topic anchors:
This setting will also automatically generate help context numbers for new topic anchors so that anchors can also be used for calls to help topics from applications.

Write translation-friendly XML

This "Tidy XML" feature significantly simplifies the XML source code of your topics, reducing the amount of tag information that needs to be written. This can make translation with XML-based tools easier but it is not compatible with earlier versions of Help+Manual.

Make sure you have a backup of your project before applying this option. Otherwise you will have trouble accessing it with earlier versions if you ever need to.

History Files:

Configure whether history files are automatically created for changed topics so that you can revert to previous versions if necessary. History files are then saved every time you save your project.

See Topic History for details.

Calculate figure tables:

This option does a preliminary generation pass of your project to calculate the numbers and captions of figures, tables and captions using the figure table references. It is needed to enable forward references to these elements to work – i.e. references to figures coming later in the project than the reference.

It is semi-automatic: If it is off and Help+Manual finds a figure table reference that needs advance calculation during export, it will stop with an error and ask you to restart. After this, it will be left on for the project until you turn it off.

Note that leaving this on will roughly double the time it takes to publish a project, so turn it off unless you really need it.

See Inserting figure links and Figure and table counters for details.

Open child projects read-only:

This protects child projects merged into the TOC of the current project against accidental editing. This is the default setting.

See Working with Modular Help Systems for more information on editing merged child projects.
