Feature value
dot command is useful to repeat the previous action without having to type the shortcut.
Currently the org-archive-subtree shortcut is <leader>o$.
If we have a dot command, archiving mutliple subtrees can be done via <leader>o$.....(the number of dots depending on the number of subtrees you want to acrhive)
