windows上安装VIM插件DrawIt！

DrawIt!是个画ASCII码图形的插件，非常好用。今天在安装时还是费了点功夫，从网上搜索了下，加上Vim官方的网站上都是这个步骤：

vim DrawIt.vba.gz
:so %
:q

这是在linux上用的，目前机器上没有安装Linux，只好将就一下，在Windows上使用了。

下载了 DrawIt.vba.gz后，按照这个说法没有办法实现画图功能，使用/di也进不了画图模式。郁闷了一阵，后来想是不是用解压后的文件，解压后是 DrawIt.vba，直接用VIM7.0打开，然后用:so %，解开了好几个scripts，退出后再次打开就可以了。

下面是一些命令：

<left>       move and draw left
   <right>      move and draw right, inserting lines/space as needed
   <up>         move and draw up, inserting lines/space as needed
   <down>       move and draw down, inserting lines/space as needed
   <s-left>     move left
   <s-right>    move right, inserting lines/space as needed
   <s-up>       move up, inserting lines/space as needed

   <space>      toggle into and out of erase mode
