How to use TeX brackets
Version: 2.5 - Scientific WorkPlace & Scientific Word
Instead of surrounding a mathematical expression with a pair of expanding
brackets, you can use TeX brackets at either end of the expression. Like any
other character, TeX brackets exist as independent objects; they behave just
like large versions of the brackets that you obtain by pressing the bracket
keys on your keyboard. If you surround an expression with TeX brackets, SW
doesn't consider your expression to be a single unit as it does when you use
expanding brackets.
To use TeX brackets, you must insert a TeX field containing a TeX bracket
command at each end of your expression. The TeX bracket command has this
syntax:
\SizeLocationSymbol\
where Size is
-
ordinary--the size of the ordinary bracket (delimiter) that you get when you
press the bracket key on the keyboard
-
big--just enough taller than ordinary so that the difference can be
perceived.
-
Big--50% taller than big.
-
bigg--twice as tall as big.
-
Bigg--2.5 times as tall as big.

\Uparrow |
double upward arrow |
\downarrow |
downward arrow |
\Downarrow |
double downward arrow |
\updownarrow |
up-and-down arrow |
\Updownarrow |
double up-and-down arrow |
Note that some symbols, including { and }, cannot be entered directly. They
must be entered as TeX macros. For example, the braces must be entered as \{
and \}.
Note too that you don't have to use a left bracket symbol for the left end or
a right bracket symbol for the right end, but you should use the l form at the
left and the r form at the right.
Here are some examples of TeX bracket commands:
-
To get a left parenthesis delimiter in the Big size, the TeX command is
\Bigl(.
-
To enter a left square bracket as a right delimiter in the Bigg size, the TeX
command is \Biggr[.
Here are the steps:
-
Place the insertion point at the beginning of the expression.
-
Make sure the insertion point is in math.
-
Enter a TeX field.
-
Enter the TeX bracket command for the left bracket.
-
Choose OK.
-
Enter your expression.
-
Enter another TeX field.
-
Enter the TeX command for the right bracket.
-
Choose OK.
