Article: This will insert an equation at the position of your cursor and open the editor. If you know the name of a symbol, simply type "\" followed by the symbol name. For example, for the Greek letter theta, type \theta and press the space bar to convert it. You can also look at https://www.rapidtables.com/math/symbols/Basic_Math_Symbols.html to preview symbol names. For example, typing "a/b" (and then pressing the space bar) puts a on top of b as a fraction. Brackets, or parentheses, (), are used to group parts of the equation in the editor. For example, "(a+b)/c" will put the expression a+b on the top of the fraction but will not display the brackets. For example, "a_b" makes b the subscript of a, and likewise, "a^b" makes b the exponent of a. Subscripts and superscripts can be used simultaneously and are also how the equation editor adds limits to integrals, for example, typing "\int_a^b" and pressing the space bar gives the integral from a to b. Trigonometric functions such as sin and arctan are recognized, as well as other functions such as log and exp; however, you must press the space bar after typing the function name in order for the editor to recognize it as a function. Font changes can be made as you are going along. To toggle bold and italic text use the normal shortcuts: Ctrl+B or Ctrl+I. To type text within an equation that looks 'normal', enclose it in quotation marks. To make a character into a script character use "\script". For example, "\scriptF" would change the F into a script character. Typing equations is much faster than selecting symbols and structures from the menu but does require learning the shortcuts. Using the steps above, you can probably guess most of the shortcuts you will need.
