A term sequence has a linear sequence of term slots. For example, one kind of sequence which happens to have 4 empty slots might be displayed as:
([elmnt],[elmnt],[elmnt],[elmnt])
. All the term slots of the sequence are considered siblings in the display form tree, and the whole sequence is their immediate parent.
The editor has special commands for inserting and deleting both elements and segments of term lists.
Different kinds of term sequences have different left and right
delimiters
, (the 
(
and 
)
respectively in the
example) and different element separators (the 
,
in the
example). Delimiters and separators in term sequences always consist of
at least one character.
