LangOver for Linux helps when you tried to type in one language but the result was in another. With LangOver you will be able to convert your text quickly between languages. LangOver is free and supports any language. LangOver can be used to convert lowercase characters to uppercase and vice versa. Select the text that you wish to convert and click "Shift + F10". If your text contains mixed cases then LangOver judges the case of the first character and converts the whole sentence according to it.
