Vim在UTF8 screen下，刪除字母的時候視窗會產生如亂碼般的錯誤，是由matchparen plugin導致的
關閉matchparen plugin的方法就是在.vimrc加入底下這行：
let loaded_matchparen = 1

vim的set和let的差別：
:set  guifont=Lucida_Console:h9:cANSI
:let &guifont="Lucida_Console:h9:cANSI"
以上兩行等價

GNU screen

給screen下指令的方式：
bound to a key, invoked from a screenrc file, or called from the colon prompt

screen畫面會閃爍的原因：visual bell

screen支援utf8的方法：
screen -U
(在existing session下執行這個指令沒用。This does not work when attaching to an existing session, you need to start a new session.)
