mark可以方便的进行跳转。比如说你当前编辑A文件的100行，你需要跳转到其他文件，一会想快速的回到A文件100行，则先在A文件100行处做一个mark。切换回来就非常方便了

ma            set mark a at current cursor location
'a            jump to line of mark a (first non-blank character in line)
`a            jump to position (line and column) of mark a
:marks        list all the current marks
:marks aB     list marks a, B



d'a            delete from current line to line of mark a
d`a            delete from current cursor position to position of mark a
c'a            change text from current line to line of mark a
y`a            yank text to unnamed buffer from cursor to position of mark a

:delmarks a       delete mark a
:delmarks a-d     delete marks a, b, c, d
:delmarks abxy    delete marks a, b, x, y
:delmarks aA      delete marks a, A
:delmarks!        delete all lowercase marks for the current buffer (a-z)
