Roughly it is good. BUT!

If I miss type in a word, I cannot do "command+a" to choose the wrong words I have typed in and delete the whole wrong word . Instead, I have to backspace the letters of the wrong word one by one.

Also, if this software can translate word on screen where the mouse pointer stay at, it will be excellent tool to use.
