 If you have included the ' item in the 'viminfo' option the jumplist will be
 stored in the viminfo file and restored when starting Vim.
 
+							*jumplist-stack*
+When 'jumpoptions' option includes "stack", the jumplist behaves like the tag
+stack.  When jumping to a new location from the middle of the jumplist, the
+locations after the current position will be discarded. With this option set
+you can move through a tree of jump locations. When going back up a branch and
+then down another branch, CTRL-O still takes you further up the tree.
 
+Given a jumplist like the following in which CTRL-O has been used to move back
+three times to location X: >
+
+     jump line  col file/text
+       2  1260    8 mark.c		<-- location X-2
+       1   685    0 eval.c		<-- location X-1
+    >  0   462   36 eval.c		<-- location X
+       1   479   39 eval.c
+       2   213    2 mark.c
+       3   181    0 mark.c
+<
+jumping to (new) location Y results in the locations after the current
+locations being removed: >
+
+     jump line  col file/text
+       3  1260    8 mark.c		<-- location X-2
+       2   685    0 eval.c		<-- location X-1
+       1   462   36 eval.c		<-- location X
+    >
+<
+
+Then, when yet another location Z is jumped to, the new location Y appears
+directly after location X in the jumplist and location X remains in the same
+position relative to the locations (X-1, X-2, etc., ...) that had been before
+it prior to the original jump from X to Y: >
+
+     jump line  col file/text
+       4  1260    8 mark.c		<-- location X-2
+       3   685    0 eval.c		<-- location X-1
+       2   462   36 eval.c		<-- location X
+       1   100    0 buffer.c	<-- location Y
