Dear Myungjae, Please take a look at commit 66118 and 66119. They introduced two new APIs evas_textblock_cursor_word_start and evas_textblock_cursor_word_end that move the cursor to the start and the end of the word respectively.
I've tested it and it works, but I can only test it to some extent, so please let me know if you find any issues. The implementation is based on the algorithm described in http://unicode.org/reports/tr29/ and was compared with the reference implementation that can be found at http://unicode.org/cldr/utility/breaks.jsp (choose word in the break options). Enjoy, Tom.
