Predefined Bookmarks
Word sets and automatically updates a number of reserved bookmarks. You
can use these predefined bookmarks just as you use the ones that you place in documents, except that you don't have to set them and they are not listed in the Go To dialog box (Edit menu). The following table describes the predefined bookmarks available in Word.
Bookmark
Description


\ Sel
Current selection or the insertion point.

\ PrevSel1
Most recent selection where editing occurred; going to this bookmark is equivalent to running the GoBack statement once.

\ PrevSel2
Second most recent selection where editing occurred; going to this bookmark is equivalent to running the GoBack statement twice.

\ StartOfSel
Start of the current selection.

\ EndOfSel
End of the current selection.

\ Line
Current line or the first line of the current selection. If the insertion point is at the end of a line that is not the last line in the paragraph, the bookmark includes the entire next line.

\ Char
Current character, which is the character following the insertion point if there is no selection, or the first character of the selection.

\ Para
Current paragraph, which is the paragraph containing the insertion point or, if more than one paragraph is selected, the first paragraph of the selection. Note that if the insertion point or selection is in the last paragraph of the document, the "\ Para" bookmark does not include the paragraph mark.

\ Section
Current section, including the break at the end of the section, if any. The current section contains the insertion point or selection. If the selection contains more than one section, the " \ Section" bookmark
is the first section in the selection.

\ Doc
Entire contents of the active document, with the exception of the final paragraph mark.

\ Page
Current page, including the break at the end of the page, if any. The current page contains the insertion point. If the current selection contains more than one page, the " \ Page" bookmark is the first page of the selection. Note that if the insertion point or selection is in the last page of the document, the "\ Page" bookmark does not include the final paragraph mark.

\ StartOfDoc
Beginning of the document.

\ EndOfDoc
End of the document.



Bookmark
Description


\ Cell
Current cell in a table, which is the cell containing the insertion point. If one or more cells of a table are included in the current selection, the " \ Cell" bookmark is the first cell in the selection.

\ Table
Current table, which is the table containing the insertion point or selection. If the selection includes more than one table, the " \ Table" bookmark is the entire first table of the selection, even if the entire table is not selected.

\ HeadingLevel
The heading that contains the insertion point or selection, plus any subordinate headings and text. If the current selection is body text, the " \ HeadingLevel" bookmark includes the preceding heading,
plus any headings and text subordinate to that heading.



The following macro demonstrates a typical use of predefined bookmarks. The macro moves line by line through a document from the current line and removes any leading spaces from the lines. The While¼Wend instruction uses the " \ Sel" (current selection) and " \ EndofDoc" bookmarks with the CmpBookmarks() function to determine whether the selection is at the end of the document. When the end of the document is reached, Word displays a message to alert the user.


Sub MAIN
StartOfLine
While CmpBookmarks("\Sel", "\EndOfDoc")
A$ = GetBookmark$("\Line")
B = Asc(A$)
If B = 32 Then DeleteWord
EndOfLine
CharRight
Wend
MsgBox "End of document."
End Sub
The CmpBookmarks() function compares two bookmarks and can return a number of different values according to the relative location and size of the bookmarks. For more information on CmpBookmarks(), see the entry in "Statements and Functions" earlier in this part.
For other examples of predefined bookmarks used in WordBasic macros,
see the following entries in "Statements and Functions" earlier in this part: CmpBookmarks(), CopyBookmark, ParaDown, Select Case.
