Notes:
•
|
International shortcut keys are provided for users whose keyboard layouts do not handle the existing keys.
|
•
|
For international shortcut keys on Macintosh, it is possible to use Opt instead of Alt.
|
|
Navigating 2-D Mathematical Expressions
|
|
Return to Baseline (Ctrl+/) returns the cursor to the top-level baseline after the structure at the current location. For example, if the cursor is several levels up in a superscript of a superscript, Return to Baseline places the cursor after the entire structure.
•
|
Scope In and Scope Out move the cursor in or out of a nested structure.
|
–
|
Scope In* descends to the first logical position within a structure, and continues deeper with further key presses.
|
–
|
Scope Out* moves the cursor to the first logical position outside of the current structure (for example, to just before a fraction).
|
|
|
Entering Greek Characters
|
|
The shortcut key combination Ctrl+Shift+G (Command+Shift+G, Macintosh) places the editor in a Greek mode, which makes the next character entered a Greek character. When Greek mode is entered, the status bar mode indicator switches to 2-D Greek.

Escaping Characters that are Shortcut Keys
|
|
Characters that are shortcut keys in 2-D math must be escaped. To enter a character corresponding to a shortcut key, such as ^, first press the backslash (\) key, then the character. For example, to display the ^ in a 2-D math region, press \ and then ^.
To enter the command in 2-D math, for example, you need to be able to enter an underscore. To enter the underscore, press \ and then _. Command completion offers another way to enter this command name.
|
|
Command Completion and Entering Symbols
|
|
Enter the name or partial name of a symbol, for example, Del (the first three characters in Delta), and then press:
•
|
Esc, Macintosh, Windows, and UNIX
|
•
|
Ctrl + Shift + Space, most UNIX platforms
|
Alternately, use the palette by clicking the corresponding palette symbol.
|
|
Entering Rationals
|
|
A rational can be entered by pressing the forward slash key (/). For example, entering a / b produces
|
|
Entering Derivatives Using Prime Notation and Dot Notation
|
|
Derivatives can be entered using the Expression palette. For example, use to create . There are also shortcuts available for prime notation and dot notation.
Prime notation for derivatives with respect to can be entered by pressing the right single quote ('). For example, entering y ' ' + y ' = 0 produces . In this example, be sure to use two right single quotes (not double quotes) to enter a second derivative.
Dot notation for derivatives with respect to can be entered by pressing the period (.) while in the overscript mode above the variable. For example, enter y, then press Ctrl+Shift+" (Command+Shift+" for Macintosh) to place the cursor in the overscript position, then enter two periods (. .) to produce . Use the right arrow to leave the overscript region after entering the dots to continue the expression. Finish the expression using the same method to produce .
|
|
Subscript versus Literal Subscript
|
|
•
|
The basic subscript, entered by pressing the underscore key (_), refers to an element of the base. For example, is the first element of the variable .
|
•
|
The literal subscript, entered by pressing <Ctrl+_>, creates a subscripted variable. For example, is a variable, and is not related to the variable .
|
|
|
Entering the Right Arrow
|
|
The right arrow can be entered as follows:
•
|
Using the right arrow in the Arrows palette
|
•
|
Entering the name RightArrow and using Command/Symbol Completion
|
•
|
Entering the dash and right chevron symbol (- + >), which automatically forms a right arrow
|
|
|
Selecting Versus Inserting Expressions
|
|
Use the forward slash (/) symbol to create a rational or the caret (^) symbol to create a superscript.
For example, to create a superscript, you can insert the cursor or select the area that is to be the base.
Example: Inserting
Enter 2bcd, and then insert the cursor between b and c. Press the ^ symbol and enter 2. An exponent (superscript) is inserted for b.
Example: Selecting Expression
Enter 2bcd, and then select 2b. Press the ^ symbol and enter 2. The selected area becomes the base for the exponent (superscript). In this case it inserts parentheses around the base.
