Here are some ways to get to what you need:
The tables of contents can be used to find the pages you need.
HMRC users can search the manual using the manual leftbar
button; however this facility is not available to Internet users.
Internet users should search using chosen keywords and
select from the results the appropriate reference. As this can take
you to detailed pages which should not be relied upon out of
context, it is strongly recommended that you press the menu button
to see the context before reading particular pages. It is important
to remember that the manual is organised in sections that equate to
the schedules applying to each scheme. If a keyword is chosen that
could apply to each of the schemes then the search result will
include references appropriate to each scheme. If guidance is being
sought in relation to a particular scheme then it is strongly
recommended that the contents page of that section is used to
locate the relevant guidance.
