好的編輯器送你上天堂，不好的編輯器送你住套房。
但是，有好的編輯器還是要有好的設定，才能送你上天堂。
同時註解多行
用virtual mode的方式選取多行
:'<,'>s/^/\/\//g把暫存器a的內的東西貼出來
"ap一般來說 :g 的運作方式是根據一行一行來做的，當你用下面指令的時候，
:g/pattern/y a這代表的意思其實只是把每次比對到的那行都 yank 複製到
"a這裡面去。所以這就會造成我們最後只會拿到最後一行的結果，而不是每個比對到的都會進入到
"a去。所以就必須告訴 vim 我們指定的內容是要做附加而不是覆蓋：
:g/pattern/y A刪除選取的行數，並且存到暫存器a
"aD或
:'<,'>d a取得目前檔案的目錄
:echo fnamemodify("%", ":p:h")%表示current file name
取得目前檔案的名稱
:echo expand("%")若執行的指令很可能會出現錯誤訊息，但仍不想要顯示錯誤訊息的話，可以使用silent，例:
:silent! exe "normal /path\<CR>"或
:silent! /xxxfdafd在目前位置加入時間
::map <F2> a<C-R>=strftime("%c")<CR><ESC>流程
1. 把目前的時間存到暫存器a
//[-start-strftime("%y%m%d")-CCD9527-remove]//
SET @a=time()
2. 註解掉目前選取的所有行數
:'<,'>s/^/\/\//g
3. 把選取的部分附加到暫存器a
"AD
4. 把目前的時間存到暫存器a
//[-end-strftime("%y%m%d")-CCD9527-remove]//
SET @A=time()
5. 把暫存器a貼到目前的位置
