The keyCulator application is the simplest calculator software in the world. However, the simplicity is both a concept and a power! This is the only calculator software without an ordinary window. Generally, there is no window at all! But how can it work? The answer is simple: keyCulator add calculation and evaluation functionality to ANY PROGRAM running. Imagine, you type in Notepad or Microsoft Word \"1+2\" and press \"=\", keyCulator will paste the evaluated Result right into document and you\'ll get \"1+2=3\". If you need only the evaluated Result, just press \"=\" once again and keyCulator will replace all typed by a Result - \"3\". If you do not need the Result in your document, but just need to know it, just press \"Esc\" and Result will be removed from document. keyCulator can be easily configured to meet your own unique needs. You can switch off Result hint window or customize Font, Color, Outline width and more. Or you can switch off Result pasting into document to just to see the Results. Auto Start with Windows feature is also supported.Limitations:
