1 Use right arrow key to leave denominator, superscript, or subscript region

 

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 in 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 Backslash (\), then the character. For example, to display the ^ in a 2-D math region, press \ and then ^.

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 in Macintosh, Windows, and UNIX

• 

Ctrl + Space in Windows

• 

Ctrl + Shift + Space in most UNIX platforms

Alternatively, use the palette by clicking the corresponding palette symbol.

Entering Rationals

When typing a rational expression, press Forward Slash (/) to enter the denominator. For example, entering a / b produces  ab.

Entering Derivatives Using Prime Notation and Dot Notation

Derivatives can be entered using the Expression palette. For example, use ⅆⅆxf to create ⅆ2ⅆ2 x yx+ⅆⅆ x yx=0. There are also shortcuts available for prime notation and dot notation.

 

Prime notation for derivatives with respect to x can be entered by pressing the right single quote ('). For example, entering y ' ' + y ' = 0 produces y''+y'=0. 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 t 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 + " in Macintosh) to place the cursor in the overscript position, then enter two periods (. .)  to produce y... 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 y..+y.=0.

Indexed Subscript versus Literal Subscript

• 

The indexed subscript, entered by pressing Ctrl + Shift + _ , refers to an element of the base. For example, x1 is the first element of the variable x (where x is, for example, a list or Matrix).

• 

The literal subscript, entered by typing Underscore twice (__), creates a subscripted variable name. For example, x1 is a variable, and is not related to the variable x.  Variables with literal subscripts are referred to as atomic variables in Maple.

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 Salsh (/) 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 Ctrl + Shift + ^ and type 2. An exponent (superscript) is inserted for b.

2 b2cd

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.

2 b2cd
