// @description Special signs are hard to remember, when writing in a foreign lang or on a different comp. Select the letter(s) and use arrow keys/wheel to switch between available options(shift to change case) Motty Katan(c) 29-09-07 updated at 15-10-07
// @include http://*
// ==/UserScript==
// Build Changes:
// 29-09-2007 now supports more than one character(case and dictionary/class). added french numbers to dictionary.
// 30-09-2007 Support of mouse wheel. Better framework - now supports capital letters in a better neater way. Vocabulary: Added Harry Potter Houses, at=@, (c),(r),tm,1/4,1/2,3/4,oe,ae
// 31-09-2007 better getUnicodeChar function.
// 04-10-2007 Shift key has other function when you select text, switching to ctrl(when shift isn't click). Load DB only if needed. Added: o,u,i
// 05-10-2007 Fixed the letter "o", added "i"
// 15-10-2007 Fixed non issue with scrool bars jumping.
//it seems that String.fromCharCode is not relaiable
