You can edit an equation as you edit text—adding, changing,
rearranging, and removing math elements, and cutting, copying, and
pasting them. As you edit an equation, the syntax of the equation
is adjusted as necessary.
You can change a matrix—add or delete rows and columns, delete
brackets, and change row height and column width. You can also choose
among several representations for some math elements such as parentheses.
You can add operands to others such as integrals and summations.
If your equation is shrinkwrapped, unwrap the equation before
editing it. This makes the anchored frame fullsized again, giving
you more room to work.
Note: To edit a rotated equation, first restore the
equation or text frame to its unrotated position by pressing Esc
g 0 (zero).
Extend a selection using the keyboard Press
the spacebar. The selection expands to include the next higher expression.
The following example shows the result of pressing the spacebar repeatedly.
Original selection


Pressed once


Pressed twice


Change the selection Do one of the following: To change
the selection to the next subexpression on the right, press the Right
Arrow key.
To change the selection to the next subexpression on the
left, press the Left Arrow key.
To change the selection to the next question mark prompt,
press Tab.
Replace or delete a math element or equationSelect the element you want to delete and press
Delete. A question mark prompt replaces the element.
Do one of the following:
To replace the element,
click the Equations panel or type to insert the replacement.
To delete the element, press Delete again. FrameMaker removes
any elements that are no longer necessary—for example, a plus sign
or parentheses.
Controlclick the equation to select the equation, and press
Delete.
Remove delimitersAfter entering or editing an equation, you sometimes end
up with extra delimiters—parentheses, curly brackets, and brackets.
You can remove extra delimiters. If you later use evaluation commands,
FrameMaker evaluates the equation as if the delimiters are still
present.
To remove all delimiters, select the expression. On the
Delimiters page of the Equations panel, click Remove Parentheses.
Before clicking

After clicking



To remove one delimiter, place the insertion point to the
right of the delimiter and press Delete. If the delimiter has a
mate, such as the left parenthesis between a and b in
the example, the mate is also removed.

Add an operand to a math elementRadical symbols, gradient symbols, and logarithms can have
one or two operands. Integrals and other symbols on the Large and
Calculus pages can have one, two, or three operands.
Operands You can add operands to these elements without starting over.
Click or select anywhere in the expression with the element.
Click Add Operand on the Large or Calculus page. A question
mark prompt appears where you specify the new operand.
Change matricesYou can change the number of rows or columns in a matrix
and add or remove brackets around the matrix. You can allow the
column width to vary from column to column, depending on the contents,
or specify that all columns are equal width. Similarly, you can
allow the row height to vary from row to row.
You can also transpose a matrix and perform matrix algebra.
To add a row or column to a matrix, place the insertion
point in the matrix. On the Matrices page of the Equations panel,
choose Add Row or Add Column from the Matrix Commands pop‑up menu.
Before Add Column

After Add Column



Add Row adds a row at the bottom. Add Column
adds a column at the far right.
To delete a row or column from a matrix, select the row or
column and press Delete.
To add or remove brackets around a matrix, select the entire
matrix. On the Matrices page of the Equations panel, click Add/Remove
Brackets.
To change the row height or column width in a matrix, select
the matrix. On the Matrices page of the Equations panel, choose
All Equal or Proportional from the Matrix Row Height or Matrix Column
Width pop‑up menu.
Equal row heights (left) and Proportional row heights (right) If you choose Proportional, each row is tall enough to hold the
tallest cell in the row. Each column is wide enough to hold the
widest cell in the column. If you choose All Equal, each row is
tall enough to hold the tallest cell in the entire matrix. Each
column is wide enough to hold the widest cell in the entire matrix.
