Brook is a keyboard trainer. Brook is a program written in VBA (Visual Basic for Applications). Therefore you have all the power of Microsoft Office Word on your hands when using Brook (Fonts, Zooming, Colors, etc). Note, Brook will not teach you how to type. There are other programs and manuals for that. Brook will only just help you to get your hand in typing. All you need to do is to copy and paste your favorite text in Brook document, press START button and begin typing. Notes for people having poor eyesight: 1) Many keyboard trainer programs do not allow you to change font size and zooming scale in a wide range of values. But Microsoft Office Word is quite another story. A wide choice of opportunities of Microsoft Office as well as the attention of Microsoft to disabled persons is a well-known fact. And using Brook as your keyboard trainer you have all the power of Microsoft Office Word because Brook is written in VBA. VBA is a programming language embedded in Microsoft Office. So, Brook is just a routine of Microsoft Office Word. 2) Let assume you are a good typist. But to read is a great deal of efforts for you because you have poor eyesight. Dr. Bates recommends his readers to watch moving objects without fixing look at them (Perfect Sight Without Glasses by William H. Bates, M. D.). Using Brook you have not to seek the next word in a text. You are just typing words while a text is moving up. Notes for learners studying foreign languages: 1) On skipping at the next word, Brook stores it in Clipboard. Thus you may use any other programs with Brook at the same time. The programs might be electronic dictionaries (ABBYY Lingvo, Oxford English Explanatory Dictionary, etc) or text-to-speech engines (2nd Speech Center, Text Aloud, etc). So, if you want to translate or hear the word that you are typing, press the key combinations you have set in those programs. Above mentioned programs just wait until the key combination is pressed and respond to the event. 2) As is known, typists remember a word in whole. Brook also compels you to remember words in the same manner.
