Bookmark the directory with the notes
Part of the reason Denote does not reinvent existing functionality is to encourage you to learn more about Emacs. You do not need a bespoke “jump to my notes” directory because such commands do not scale well. Will you have a “jump to my downloads” then another for multimedia and so on? No.
Emacs has a built-in framework for recording persistent markers to locations. Visit the denote-directory (or any dir/file for that matter) and invoke the bookmark-set command (bound to ‘C-x r m’ by default). It lets you create a bookmark.
The list of bookmarks can be reviewed with the bookmark-bmenu-list command (bound to ‘C-x r l’ by default). A minibuffer interface is available with bookmark-jump (‘C-x r b’).
If you use the ‘consult’ package, its default consult-buffer command has the means to group together buffers, recent files, and bookmarks. Each of those types can be narrowed to with a prefix key. The package ‘consult-dir’ is an extension to ‘consult’ which provides useful extras for working with directories, including bookmarks.
