最新发现的Vim里面的一些不太常用，但是非常强大的功能，包括列选定，分屏等等，学习并记录之。
这个思维导图来自于Joe Marinez的blog
摘录下来从中学到的几个命令：
Marking Text：
v = start visual mode
V = start linewise visual mode
ctrl-v = start blockwise visual mode
o = move to other end of marked area
U = upper case of marked area
O = move to Other corner of block
> = shift right
< = shift left
y = yank
d = delete
~ = switch case
Multi-File:
:sp fn = open a file in new buffer and split window
ctrl-w s = split window
ctrl-w w = switch windows
ctrl w - window commands
ctrl-w q = quit a window
ctrl-w v = split windows vertically
Tab Commands:
:tabe fn = edit file in new tab
gt = next tab
gT = previous tabs
:tabr = First tab
:tabl = Last tab
:tabm [N] = move current tab after tab N
