Such is the idea. Born again for a long time. Well, now I'm finally going to introduce you to her. The idea is quite banal.
The problem is widely known - the keyboard layout, sometimes very angry. It has long been in wide use there is a bunch of software like the most popular
Punto Switcher . However, not everyone uses them, and even these programs themselves periodically get angry no less. The principle of work - to change the layout on the go. This is especially important in the case when the text is typed by us - it is important that it be saved / sent / processed. Another thing - Instant Messaging. Here we are talking about messages that have already been sent, which we do not have the ability to edit. Imagine that a message was sent in the wrong layout, but because this is a quick messaging, then almost always the only thing we need is to read the message only once.
I offer just such a scheme:

')
As a result, we get a small plug-in (in my example, to Miranda), which will simply convert the characters from “qwerty” to “Yukuken”. Significantly accelerated messaging.
ps Itself is not a programmer, I can only be scattered with ideas.
