selenium.keypressnative doesn't seem to work

I am trying t开发者_如何学Co simulate a keypress for enter key in selenium using the below statement:

Selenium.KeyPressNative("10");

It works on my colleague's PC, but, doesn't seem to be executed in my machine. It appears that selenium skips this command.

Please help.

Thanks and Regards,
