Use right arrow key to leave denominator, numerator, 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 Mac, 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 Mac) 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 Mac, Windows, and Linux
 • Ctrl + Space in Windows
 • Ctrl + Shift + Space in Linux

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

Entering Rationals

When typing a rational expression, the preceding term can be used for either the numerator or the denominator.

 • Press / (forward slash) to use the preceding term for the numerator, and then enter the denominator. For example, entering a / b produces $\frac{a}{b}$.
 • Press // (two forward slashes) to use the preceding term for the denominator, and then enter then numerator. For example, entering a / / b produces $\frac{b}{a}$.
 Entering Derivatives Using Prime Notation and Dot Notation Derivatives can be entered using the Expression palette. For example, use $\frac{ⅆ}{ⅆ\phantom{\rule[-0.0ex]{0.2em}{0.0ex}}{x}}{f}$  to create $\frac{{ⅆ}^{2}}{ⅆ{x}^{2}}y\left(x\right)+\frac{ⅆ}{ⅆx}y\left(x\right)=0$. 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 Mac) to place the cursor in the overscript position, then enter two periods (. .)  to produce $\stackrel{..}{y}$. 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 $\stackrel{..}{y}+\stackrel{.}{y}=0$.

Indexed Subscript versus Literal Subscript

 • The indexed subscript, entered by pressing Ctrl + Shift + _ , refers to an element of the base. For example, ${x}_{1}$ 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, $\mathrm{x__1}$ 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 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 2b c d, and then insert the cursor after b. Press Shift + ^ and type 2. An exponent (superscript) is inserted for b. Example: Selecting Expression Enter 2b c d, and then select 2b. (You can make a selection by holding down Shift and using the left/right arrow keys.) 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.
