### Key Concepts

This section will present two important concepts for working with MathCast, Rapid Mathline and Equation List Management.

#### The Rapid Mathline

Typing equations into MathCast is really simple and is done through a text input line called Rapid Mathline. You type-in an equation as you would to a calculator, and MathCast automatically formats your equation to appear as it would on paper. MathCast's engine is smarter than calculators' though, so the equations you insert in the Mathline are human-logically readable.
The Rapid Mathline supports keyboard hotkeys to be used with the Ctrl key and another key. And pressing a normal key on the keyboard twice or more inserts Greek letters and mathematical symbols. In addition to that, the Rapid Mathline is nicely integrated into the Edit Screen, which has more tools for inserting mathematical symbols and functions.
For advanced formatting, such as: underscript, bold, and others, MathCast has special markup characters, which allow you to specify how the output would look.

#### Equation List Management

MathCast is an Equation List Manger: Equations are kept in lists, and you as the editor can work on each equation individually or on all equations at the same time. This powerful concept enables you to work on all the mathematics of your project, be it a document, a webpage, or something else, all at the same application, which is unique to mathematics.
Using the Rapid Mathline, you can type-in new equations into the list. If you are working on a new equation that is similar to one you already have in the list, you can copy the other equation, or a part of it, into your new equation and make the appropriate changes.
Equations can be moved around the list or deleted from it.
You can even work on a list together with a friend over a LAN or across the Internet.
When needed, you can copy an equation to the clipboard, and paste it into your project.
You can, of course, save lists to and open lists from files on your hard drive.
