keyCulator 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 a program
window. Actually, there is no window at all! But how
can it work? The answer is simple: keyCulators add
calculation functionality to ANY RUNNING PROGRAM.

Imagine you are typing "1+3" in a Notepad or MS Word
document and hitting "=". keyCulator will paste the
result right into the document and you'll get "1+2=3".
If you need only the result, just press "=" once again
and keyCulator will replace all the characters typed
by "3", the result. If you do not need the result in
your document, but just need to know it, simply
press "Esc" and the result will be removed from
document.
