Entering Input in Notebooks
Mathematica's notebook interface is a very powerful typesetting system that allows you to enter formulas as they are written in mathematical literature, using two-dimensional notation such as superscripts, subscripts, and so on.
Mathematical symbols and two-dimensional notation can be entered from the keyboard as well as through palettes.
Formulas entered in two-dimensional form can be used for input in Mathematica.
|power||x Ctrl+^ 3||x3|
|fraction||x Ctrl+/ 3|
|square root||Ctrl+2 x|
|subscript||x Ctrl+_ 3||x3|
|move cursor out of formula by one level||Ctrl+Space|| |
You can use Ctrl+6 as an alternative to Ctrl+^; on some non-U.S. keyboards, you may have to use Ctrl+6.
Note that on some operating systems, if the main Ctrl key is remapped, the keyboard commands discussed here will not work.
You can use formulas entered in two-dimensional form for input in Mathematica.
Powers and Fractions
Type , then press Ctrl+^ to create the placeholder for the power.
Type the power , then press Ctrl+Space to move the cursor out.
Similarly, type , then the numerator of the fraction, , then Ctrl+/ to create the placeholder for the denominator.
Type the denominator and then press Ctrl+Space to complete the task.
You can select and edit any part of a two-dimensional formula.
Tables and Matrices
Tables and matrices can be entered using the command . In the dialog box, specify the number of rows and columns. Press Tab to fill in successive entries.
Tables can also be entered directly from the keyboard.
|add a column||Ctrl+,|
|add a row||Ctrl+Enter|
|move out of table||Ctrl+Space|
Editing in a table or matrix.
Type parentheses around a table to display it as a matrix.
You can use Grid to preserve or create a matrix structure in evaluations.
Every special character in Mathematica has a full name, such as \[Alpha]. Common characters also have short aliases using the Esc key.
| (differential operator)||\[DifferentialD]||EscddEsc|
You can enter the character using the full name, \[Alpha]. Once the closing square bracket is typed, the character is substituted for the full name.
You can also enter a character using its Esc alias. EscbEsc is the alias for .
Esc appears on the screen as and disappears when the substitution occurs.
Certain special characters are replaced automatically without pressing the Esc key. For example, is converted to .
You can also use TeX names as aliases for special characters, such as Esc\inftyEsc.
You can get a list of all special characters by choosing . The name of each character is displayed in a tooltip when the cursor is over the character.
