todo-mode: File Editing

 
 5.1 File Editing and Todo Edit Mode
 ===================================
 
 There are four file-level editing commands:
 
 ‘F a’
      Add a new todo file (‘todo-add-file’).  This command prompts for a
      name and creates the file in ‘todo-directory’, adding the ‘.todo’
      extension (so you should not include the extension in the name you
      enter).  The command also prompts for the file’s first category
      and, if option ‘todo-add-item-if-new-category’ is enabled (the
      default), for that category’s first item.
 
 ‘F r’
      Rename the current todo file (‘todo-rename-file’).  If called with
      a prefix argument, prompt for a todo file and rename it.  If the
      todo file has an archive (SeeTodo Archive Mode) or there are
      corresponding filtered items files (SeeTodo Filtered Items
      Mode), this command renames these accordingly.  If there are live
      buffers visiting any of these files, the command also renames them
      accordingly.
 
 ‘F k’
      Delete the current todo file (‘todo-delete-file’).(1)  If the todo
      file has an archive (SeeTodo Archive Mode), prompt for whether
      to delete that as well.  This command also kills the buffers
      visiting the deleted files.
 
 ‘F e’
      This command (‘todo-edit-file’) changes the buffer’s major mode to
      Todo Edit mode.  In this mode the entire file is visible, the
      buffer is writable and you can use the self-insertion keys and
      standard Emacs editing commands to make changes.  To return to Todo
      mode, type ‘C-x C-q’ (‘todo-edit-quit’).
 
      The command ‘F e’ is not intended for normal editing of items and
      categories, as it circumvents the restrictions that Todo imposes to
      protect against file format corruption (i.e., all categories, not
      just the current one, and all internal formatting are exposed and
      editable).  It is provided primarily as a convenience for two types
      of use cases that are likely to arise infrequently.  One is to be
      able to use standard Emacs commands like ‘query-replace’ to replace
      a piece of text that occurs in different categories throughout the
      file.  The other use case is to recover from a mistake, such as
      accidentally deleting an item, since this cannot be undone in Todo
      mode.
 
      Using ‘C-x C-q’ to quit Todo Edit mode provides a measure of
      safety, since it runs a file format check, signaling an error if
      the format has become invalid.  However, this check cannot tell if
      the number of items or categories changed, which could result in
      the file containing inconsistent information (see the cautionary
      note in SeeReordering Categories, for more details).  Invoking
      ‘F e’ displays a warning to this effect.

    (1) The key binding of this command is mnemonic for “kill” to
 parallel the binding ‘k’ for item deletion, since ‘d’ is bound to
 another item editing command (SeeDone Items).
