todo-mode: Reordering Categories
8.2 Reordering Categories
=========================
Todo Categories mode provide commands with which you can change the
numbering of the categories in the current file. This renumbering has
the effect of reordering the categories for sequential navigation by ‘f’
and ‘b’ in Todo mode and Todo Archive mode. These commands are only
operative when the table displays the categories in their numerical
order. They work just like reprioritizing items in Todo mode, hence
have the same key bindings:
‘r’
Raise the current line of the table (the one the cursor is on),
decreasing the category’s number by one (‘todo-raise-category’).
This command exchanges lines, and hence the numbers, of the
category at point and the one above it before invoking the command.
‘l’
Lower the current line of the table, increasing the category’s
number by one (‘todo-lower-category’). This command exchanges
lines, and hence the numbers, of the category at point and the one
below it before invoking the command.
‘#’
Prompt for a number between 1 and the number of categories in the
file and reorder the table accordingly
(‘todo-set-category-number’). If called with a numeric prefix
argument within the allowed range, reorder the table without
prompting.
The reordering done by these commands remains in effect when you
return to Todo mode or Todo Archive mode and, as long as you save the
todo or archive file after reordering, in subsequent sessions as well.
*Caution*: It is important to be aware that renumbering the
categories does not change the textual order of the categories in
the file. This is significant if you should invoke ‘F e’ to edit
the entire file manually and in so doing alter the number of
categories or the number of items in a category: this will make the
information shown in the table of categories of this file
inconsistent with its actual state. You can repair this
inconsistency by invoking the command ‘todo-repair-categories-sexp’
(which lacks a key binding, since it is meant to be a rarely needed
rescue operation). But this will revert any renumbering of the
categories you have made, so you will have to renumber them again.
This is one reason why you should exercise caution when using ‘F
e’.
