There are two additional toggle commands that affect display in the current file:
Hide the item headers if visible, or show them if they are hidden. With done items, only the done header (i.e., the done tag and date-time string inserted when the item was marked done) is hidden, the original date-time string is not. With filtered items, the category (or category-file) tag is not hidden.
Highlight the current item (with the face hl-line) if
unhighlighted, or remove its highlighting. When item highlighting is
enabled, it follows navigation by n or p. If you want to
have current item highlighting by default, enable the option
todo-highlight-item. F H or H will still toggle
it.
There are two options which affect the display of items whose content is longer than one screen line:
todo-indent-to-here sets the amount of indentation for all lines
after the first in multiline todo items, which is necessary in order
for todo diary items to be fully visible in the Fancy Diary display.
The default indentation is 3 spaces. For a uniform appearance this
option applies to all items, i.e., diary and nondiary todo items and
also done items.
todo-wrap-lines allows you to choose, for the purposes of
insertion and editing, between treating multiline todo items as
containing multiple logical lines with hard line breaks or as multiple
visual lines using Visual Line mode; the latter is the default. Since
multiparagraph items also contain hard line breaks in Visual Line mode,
for a uniform appearance this display shows indentation on wrapped lines
by using a wrap-prefix of todo-indent-to-here spaces.
The indentation inserted after a hard newline is actually a tab
character, and the Todo modes that display items bind tab-width to
todo-indent-to-here, so if you change the default value of the
latter, the next time you visit a Todo file, the indentation will
reflect your change.
By default, the todo and done items sections of a todo category are
visually separated by a line as wide as the window the buffer is
displayed in. You can change the appearance and width of the separator
by customizing todo-done-separator-string; you can also change the
face of the separator string (todo-done-sep).
There are also several options for changing the appearance in Todo
Categories mode and Todo Filtered Items mode, beyond those mentioned
above in the sections on these modes; see the customization groups
todo-categories and todo-filtered for details.
