Overview

How to type

Start with the expression that will be the numerator.

Type x

Create a built-up fraction by pressing the Control and Slash keys at the same time. The placeholder in the denominator is already selected.

Press ControlKeyLeftModified/ RightModified

Fill in the denominator.

Type y

Move the insertion point out of the fraction by pressing the Control key and the Space bar at the same time.

Press ControlKeyKeyBarSpaceKey

How to type

Start with the expression that will be the base.

Type x

Create a built-up power by pressing the Control key and the 6 key (or the Caret key) at the same time.

Press ControlKeyLeftModified6 RightModified or ControlKeyLeftModified^ RightModified

Type the exponent into the placeholder (which is already selected).

Type m

Move the insertion point out of the exponent down to the baseline by pressing the Control and Space keys at the same time.

Press ControlKeyKeyBarSpaceKey

How to type

To get a square root sign, press the Control key and the 2 key (or the @ key) at the same time.

Press ControlKeyLeftModified2 RightModified or ControlKeyLeftModified@ RightModified

Type inside the placeholder (which is already selected).

Type x

Press the Control key and the Space bar at the same time to get out of the square root.

Press ControlKeyKeyBarSpaceKey

How to type

To get a radical, press the Control key and the 2 key (or the @ key) at the same time.

Press ControlKeyLeftModified2 RightModified or ControlKeyLeftModified@ RightModified

Type the radicand inside the placeholder (which is already selected).

Type x

Press the Control and 5 key (or the % key) at the same time.

Press ControlKeyLeftModified5 RightModified or ControlKeyLeftModified% RightModified

Type the index.

Type n

Get out of the radical and down to the baseline by pressing the Control key and the Space bar at the same time.

Press ControlKeyKeyBar SpaceKey

How to type

Type a left parenthesis and a right parenthesis, then move the insertion point to be between them.

Type (), press

Type the first entry of the vector. Create a new column by pressing the Control key and the Comma key at the same time.

Type a, press ControlKeyLeftModified, RightModified

Type the next entry into the placeholder (which is already selected). Create a new row by pressing the Control key and the Return key at the same time.

Type b, press ControlKeyLeftModified RightModified

Type the next entry into the placeholder (which is already selected). Press the TabKey key to select the next placeholder.

Type c, press TabKey

Type the last entry into the placeholder. Press the Control key and the Space bar at the same time to get out of the GridBox.

Type d, press ControlKeyKeyBarSpaceKey

Move the insertion point to get out of the matrix.

Press

How to type

Type the symbol that will have the subscript.

Type x

Create a subscript by pressing the Control key and the - key (or the _ key) at the same time.

Press ControlKeyLeftModified- RightModified or ControlKeyLeftModified_ RightModified

Type the subscript into the placeholder (which is already selected).

Type i

Move the insertion point out of the subscript position up to the baseline by pressing the Control and Space keys at the same time.

Press ControlKeyKeyBarSpaceKey

How to type

Type the symbol that will have the superscript.

Type A

Create a superscript by pressing the Control key and the 6 key (or the Caret key) at the same time.

Press ControlKeyLeftModified6RightModified or ControlKeyLeftModified^ RightModified

Type the superscript into the placeholder (which is already selected).

Type T

Move the insertion point out of the superscript position down to the baseline by pressing the Control and Space keys at the same time.

Press ControlKeyKeyBarSpaceKey

How to type

Type the expression that will have an underscript.

Type x

Create an underscript by pressing the Control key and the = key (or the + key) at the same time.

Press ControlKeyLeftModified= RightModified or ControlKeyLeftModified+ RightModified

Type an underscore into the placeholder (which is already selected).

Type _

Move the insertion point out of the underscript position up to the baseline by pressing the Control and Space keys at the same time.

Press ControlKeyKeyBarSpaceKey

How to type

Type the expression that will have an overscript.

Type x

Create an overscript by pressing the Control key and the 7 key (or the & key) at the same time.

Press ControlKeyLeftModified7 RightModified or ControlKeyLeftModified& RightModified

Type an underscore into the placeholder (which is already selected).

Type _

Move the insertion point out of the overscript position down to the baseline by pressing the Control and Space keys at the same time.
