字符按键表，

driver.find_element_by_id("kw").send_keys(Keys.BACK_SPACE)


send_keys(Keys.BACK_SPACE) 删除键（BackSpace）
send_keys(Keys.SPACE) 空格键(Space)
send_keys(Keys.TAB) 制表键(Tab)
send_keys(Keys.ESCAPE) 回退键（Esc）
send_keys(Keys.ENTER) 回车键（Enter）
send_keys(Keys.CONTROL,'a') 全选（Ctrl+A）
send_keys(Keys.CONTROL,'c') 复制（Ctrl+C）
send_keys(Keys.CONTROL,'x') 剪切（Ctrl+X）
send_keys(Keys.CONTROL,'v') 粘贴（Ctrl+V）

 下面的是send_keys的帮助文档，可以传入将要输出的string对象，或者是一个按键集合。

Help on method send_keys in module selenium.webdriver.remote.webelement:

send_keys(*value) method of selenium.webdriver.remote.webelement.WebElement instance
    Simulates typing into the element.

    :Args:
        - value - A string for typing, or setting form fields.  For setting
          file inputs, this could be a local file path.

    Use this to send simple key events or to fill out form fields::

        form_textfield = driver.find_element_by_name('username')
        form_textfield.send_keys("admin")

    This can also be used to set file inputs.

    ::

        file_input = driver.find_element_by_name('profilePic')
        file_input.send_keys("path/to/profilepic.gif")
        # Generally it's better to wrap the file path in one of the methods
        # in os.path to return the actual path to support cross OS testing.
        # file_input.send_keys(os.path.abspath("path/to/profilepic.gif"))
