Help ID

A Help ID is a unique identifier used to display context sensitive help.

In general, all icons in the toolbars have Help IDs, all menu commands, and all controls in dialog boxes. When a user activates Extended Tip Help and points to any of these objects, the application shows the respective help text from the help source files. The link between application and help is the Help ID.

Help IDs are defined by the OOo developers when they write the code. Most often this is an automatic step of their work.

Currently, many Help IDs exist in two types - as a number or a character string. The new UNO Help IDs, used mainly for menu commands, only have strings starting with .uno:

The Online Help uses a file 'help_hid.lst' which lists Help IDs. This file is used when compiling the Help to generate a binary index file for fast access of the help text. A typical line of this file:

SID_ATTRIBUTES_LINE,10143,.uno:FormatLine

The string SID_ATTRIBUTES_LINE most often is a legacy Help ID no longer in use, if an UNO ID exists. But you cannot be sure...

The number 10143 is used whenever the command (which may be Format - Line or such) is a part of a context menu.

The .uno:FormatLine string is used within menus and in dialog boxes, if applicable.
