Symbol

Use this dialog to insert a symbol by using its name or numerical code. You can then preview the symbol or insert it into the equation by clicking the "OK" button.

Character Name

Under the Name tab, you may select from any one of the recognized names located in the drop-down list.

Unicode

Under the Unicode tab, you may enter either a Hexadecimal or Decimal number.

Hexadecimal Number

This should be the Unicode value for the symbol. Again, a list of the codes of named symbols is on the MathFlow Named Characters page. However, you are not limited to these named symbols. Any symbol that is represented in the font used will be displayed.

Decimal number

This is the decimal version of the hexadecimal unicode. If you want to ensure that you have entered the reference for the right symbol, press Enter or click the "Preview" button after entering it. You will see a symbol appear in the white area on the right part of the Insert Symbol dialog box. There are several possibilities here:

A red square with diagonals -- this means you either entered a name not in the list of MathFlow Named Characters, or have used a non-existent numerical reference.

A black rectangle -- this means you entered a numerical code that is not in the font in use, and hence cannot be displayed. You can still insert this code, but will not be able to see it in the formulas.

A symbol -- this is what you will get if you insert it in the formula.

After choosing the correct symbol, click the "OK" button, and it will be inserted into the Editor, at the cursor position.
