Math Data Entry Shortcuts

MegaMath includes quick data entry shortcuts for six of the most commonly entered kinds of expressions. We list them below. Note that pressing Alt-Q toggles on or off the ability to use these quick data entry shortcuts, as well as those given in fastmath.meg.

To enter a fraction, with numerator of X and denominator of Y, you can type:

• [X//Y] (left bracket, numerator, slash slash, denominator, right bracket)

For example, you can enter one half as:

• [1//2]

You can enter one and two thirds as:

• 1[2//3]

To enter a superscript of X, you can type:

• ^[X] (if X is a single character, then you don't need the brackets around it)

For example, you can enter x squared, or x to the power 2 (x with a superscript of 2) as:

• x^2

You can enter x to the power n+1 (x with a superscript of n+1) as:

• x^[n+1]

To enter a subscript of X, you can type:

• _[X] If X is a single character, then you don't need the brackets around it.

For example, you can enter x with a subscript of 3 as:

• x_3

You can enter x with a subscript of 2n-1 as:

• x_[2n-1]

To enter X within a radical, you can type:

• v[X]

For example, you can enter the square root of 5 as:

• v[5]

You can enter the square root of x squared plus one as:

• v[x^2+1]

To enter the expression A above the expression X, you can type:

• [X]^^[A] If the expression X or A is a single character, then you don't need the brackets around it.

To enter the expression B below the expression X, you can type:

• [X]__[B] If the expression X or B is a single character, then you don't need the brackets around it.
