[qet] speed up the writing of translations

[silvio <silvio.qet@xxxxxxx>]

Hallo,
I wish it was easier and faster the translation the name of the element, 
without using the mouse, but only the keyboard.

example:
CTRL + E     opens the dialog (Edit Name)
+ Adds a line and the focus goes on the language fild on the left (such 
as clicking with the mouse)
TAB the focus goes to the right field
TAB the focus goes to the bottom buttons (add line, cancel, OK)
ENTER        Press the button focused

Is possible to have in next realese, or it's too complicated? Need an 
image to explain better?

Regards.
Silvio
