没分了...求高手简洁代码，合并函数.没分了 ,不好意思...

有没有办法可以把theforever1，theforever2，theforever3，theforever4 合并为一个函数，且功能正常，能合并setTab函数更好...。这样一个个调用太杯具了.
还有点小问题想请教: 1.为什么在Firefox中锚链接定位目标后为什么不能聚焦且全部选中。
2.Firefox多行文本框为什么没有下拉条（是不是内容多了就会出现呢？....）
3.顺便问下JS里面有没有能点击事件后响应键盘的功能 比如点击一个事件后 键盘自动Ctrl+C
帮帮我吧 在不搞定我就杯具了...<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" >
