Answer 1

In Chrome4, certain control key combinations have been reserved for browser usage only and can no longer be intercepted by the client side JavaScript in the web page.
These restrictions did not exist in Chrome3 and are inconsistent with both Firefox3/3.5 and IE7/8 (on Windows).

These combinations cannot get captured by Javascript, but embed plugins can capture these. For example if you focus in a Youtube video and press Ctrl+T, the browser won't open a new tab.

Answer 2

系统级别的操作还是不要去折腾了，你总不能禁止ctrl+c去复制吧

Answer 3

什么浏览器？有些浏览器，比如chrome是拦截不到ctrl+t的。
