last time i using IE7.0,when i post reply in this forum.
i just need to click Alt + S to add reply.
but now i using Opera,and i think Alt + S no work in this Browser.
do u know what is the shortkey for this opera?

Actually no I don't. But it must be in here somewhere, I just decided not to read it all.
Use Opera without a Mouse (http://www.opera.com/support/tutorials/nomouse/)

and last question is "any download software work for opera"
now i using "thunder 5",when i use ie7 and click on the download link.
this software popup and start download.
but opera just download in the opera browser....

Opera includes a built-in download manager, but sadly not fully compatible with all websites.

Here's all Opera's pluggins (http://www.opera.com/docs/plugins/), just scroll down to "Download Organizers" to use the ones recommended.

Here's a pay for one that looks good: http://www.freedownloadscenter.com/Network_and_Internet/Download_Managers/Internet_Download_Manager.html

I hope that's 3 out of 3 :)
