 \section{User commands}
 There are currently three commands to set superscript and subscript. Their format can be set temporarily using the optional parameters of the command, or set globally using a key-value list, see section \ref{sec:global control interface}.
 \begin{commands}
-  \command{super}[\oarg{kv list}\marg{content}\oarg{kv list}]
+  \command{super}[\sarg\oarg{kv list}\marg{content}\oarg{kv list}]
   This is a superscript output command. The two \meta{kv list} are equivalent.
-  \command{sub}[\oarg{kv list}\marg{content}\oarg{kv list}]
+  \command{sub}[\sarg\oarg{kv list}\marg{content}\oarg{kv list}]
   This is a subscript output command. The two \meta{kv list} are equivalent.
-  \command{supersub}[\oarg{kv list}\marg{super cont}\marg{sub cont}\oarg{kv list}]
-  This is a command that outputs both superscript and subscript at the same time. You can also use the shorter command \cs{spb} instead of it. The two \meta{kv list} are equivalent.
-  \command{defspbstyle}[\marg{style name}\marg{kv list}]
-  Defines the style of the superscript or subscript used for the \option{style} option.
-  \command{spbifmath}[\marg{math code}\marg{text code}]
-  In some cases, \code{math} or \code{text} output modes require different code for format or move. This command can be used when using the \code{match} option or changing the output mode locally, whitch should be used in the move or format options. It can switch the corresponding code according to different output modes.
 
   When the horizontal movement distance of the marker is \emph{non-negative}, since the \cs{super} and \cs{sub} commands put the marker in a horizontal box, the horizontal position is staggered when using superscript and subscript \emph{consecutively}, which is a different mechanism than the sequential use of \code{\^{}} and \code{\_} symbols in math mode. The following three commands save the width of the previous marker, use it for negative move of the \option{hmove} option of the next marker, and provide the corresponding alignment.
 
   It should be noted that the following commands should save the longer width of the marker, that is, the longer width of the marker in the front, the shorter width of the marker in the back. This is due to the fact that horizontal movement uses a negative distance to leave the marker in a zero-width box state.
   \command{llastwd}\newtag%
-  Save the width of the previous marker and provide left alignment.
+  Save the width of the previous marker and provide left alignment. This is actually the width of the previous marker, and is the same as the value of \cs{rlastwd} after the next command is used.
