+>

+Follow named anchors ~
+
+This feature allows the 'ge' command to follow named anchors in links of the
+form 'file#anchor' or just '#anchor', where file may omit the '.md' extension
+as usual. Two variables control its operation:
+>
+  let g:vim_markdown_follow_anchor = 1
+<
+This tells vim-markdown whether to attempt to follow a named anchor in a link
+or not. When it is 1, and only if a link can be split in two parts by the
+pattern '#', then the first part is interpreted as the file and the second one
+as the named anchor. This also includes urls of the form '#anchor', for which
+the first part is considered empty, meaning that the target file is the current
+one. After the file is opened, the anchor will be searched.
+
+Default is '0'.
+>
+  let g:vim_markdown_anchorexpr = "'<<'.v:anchor.'>>'"
+<
+This expression will be evaluated substituting 'v:anchor' with a quoted string
+that contains the anchor to visit. The result of the evaluation will become the
+real anchor to search in the target file. This is useful in order to convert
+anchors of the form, say, 'my-section-title' to searches of the form 'My
+Section Title' or '<<my-section-title>>'.
+
+Default is "''".

+You can adjust a new list indent. For example, you insert a single line like

+<
+This is super useful for GitLab and GitHub wiki repositories.
