Getting to Know Booki – Tutorial #7: Symbols and Formulas
Symbols and Formulas can be quite important in generating content for books, symbols give you access to a wide range of characters that get used in language but aren’t available on the keyboard (such as ° in 23°C). Formulas take things a step further allowing you to arrange your symbols in a specialist layout that isn’t available with general typing.
Adding Symbols to documents using Web-based editors has often been a hassle. Most of these editors don’t have an insert symbol button so you would have to open up a Word Processor, use it’s insert symbol feature to add the symbol you need and then copy and paste the symbol from the word processor to the Web-based editor. While this does work, it is a roundabout method and if you’re writing a scientific book which includes lots of Greek letters in formulas it can become a real pain.
Fortunately Booki’s editor has a built-in Insert Special Character function so you never have to leave the editor when you need to insert μ, β, ºC or any other special character that you require.
Simply open up a chapter of your book in edit mode and press the Insert Special Character button on the toolbar. Now click on the Character that you want, when you have finished close the Insert Special Character window.
The Formula Editor is like a special case of Insert Special Character. The formula gives you access to the full range of Greek Letters, Mathematical Symbols and Special equation Layouts. This is useful when writing a Serious scientific publication using Booki.
To access the Formula Editor click on the formula editor button.
This opens up the Formula Editor Window
The top section of the window allows you to insert special layouts for your equation.
The middle section is a large selection of special characters for use in mathematics.
The bottom section is split into two halves: on the left is the Input panel where you enter the values into your equation and on the right is Preview panel showing how the equation will look when rendered.
To enter a formula start typing in the Input panel, if you need a special equation layout click on the appropriate layout and it will be added to the Input panel. If you need a special character click on the appropriate character and it will be added to the end of your equation. You will notice in the above example that special characters are given specific names in the Input panel which render as the appropriate character in the Preview panel (in this case the word alpha is rendered as the character α).
If you need a special character inserted into the middle of a layout, move the cursor to the appropriate position in the Input panel, delete any original characters that need removing and then type in the name of the special character you need.
When you have finished your formula, scroll down to the very bottom of the Formula Editor window and click OK to insert it into your chapter.
