For example, after editing [` + "`" + `/grocery` + "`" + `](/grocery), goto [` + "`" + `/grocery/list` + "`" + `](/grocery/list). In this page, whatever you click on will be striked through and moved to the end. This is helpful if you write a grocery list and then want to easily delete things from it.
