14.2.5. Changing the structure
You may want to change the structure of an existing expression, such as appending a superscript, putting
parentheses around an expression, or turning an expression into the numerator of a fraction. To do that,
select the expression and enter the new construct with the Math palette, the Insert/Math submenu or the
keyboard.
You can also use Transform from the Tools menu. Select the expression you want to transform and
Transform will display a menu with all possible changes. For constructs that are not part of the
Presentation MathML markup - i.e. only available from the palette - clicking on the button will put the
selected expression in the most natural placeholder.
Changing an expression is useful to keep a recursive structure even when you enter a formula linearly.
For instance to enter
x
2
≤
9
25
⇒
x ≤
3
5
you can,
• either enter "recursively" (faster but less natural for long expression) :
⇒
≤
⇒
≤
⇒
x ≤
⇒
x
2
≤
⇒
x
2
≤
⇒
x
2
≤
9
⇒
◦ ...
• or enter "linearly" (you write as you read, but you need to select several times) :
x x x
2
x
2
≤ x
2
≤ 9 x
2
≤
9
◦ ...
Generally, you will use both methods.
14.2.6. Viewing structure in MathML
A MathML structure in a document can be viewed by choosing Show Structure from the Views menu.
Choosing this option opens up the Structure view, which reveals the main structure of the document, the
math elements, and their contents.
Math expressions can be edited in the main view or in the structure view.
The structure view is especially helpful to avoid ambiguity. For example, in the equation below, placing
the cursor after character
b
, it is not clear whether you wish to add something within the square root or
after it.
x =
√
a + b + 1
Selecting (or checking) in the Structure view avoids any misselections. You can also check the status line
at the bottom of the window.
14.2.7. Linking in MathML
You can create and use links in mathematical expressions. These links are represented using the XML
Linking Language (XLink). Only simple unidirectional hyperlinks are available in Amaya, but you can
associate a link with any part of a formula. For example, the fraction in the formula below is a link to the
W3C home page:
y =
1
√
x
2
+ 1
Double-clicking or right-clicking any character within the fraction loads the W3C home page.
To create such a link, select a math expression (the fraction in the above example, for instance by
clicking on the fraction bar), click the button from the Elements tool, or choose Create or change
link from the Links menu, and click the desired target.
