### 2014-04-28 1.0.0.1

作为Mac用户，经常使用[keycastr](https://github.com/sdeken/keycastr)，一个开源的按键显示软件，来录制各种技术演示视频。
同时身为一名Windows用户，在网上搜过Windows下的同类软件，是有一些，但没有一个像keycastr一样让我满意。

2014年三月的某天，我最终决定自己整一个 —— KeyCastOW，最后的`OW`表示On Windows.

基于某些原因（我还是希望有人能购买的），这个不开源，但是免费。

下面用Windows下gVim[我的vim配置](https://github.com/brookhong/vimfiles)做些演示。
注：我的`<leader>`是`s`，所以当你在normal mode下看到一些s开头的命令时，也不用奇怪。我还有一些命令是以空格开头的。

以上演示使用[LICEcap](http://www.cockos.com/licecap/) 和 [KeyCastOW](/assets/downloads/keycastow.zip)制作。
请自行获取[源码](https://github.com/brookhong/KeyCastOW)编译。

### 2014-04-28 1.0.0.1

As MAC user, I use [keycastr](https://github.com/sdeken/keycastr), an open-source keystroke visualizer to create tech demo animation.

I'm also a Windows user, I googled alternatives of keycastr for windows several times.
There are some, but none makes me happy like keycastr from MAC.

Thus one day in March of this year(2014), I finally started my own one -- KeyCastOW, the `OW` after keycast means On Windows.

For some reasons, this is not open-sourced, but it's free.

For demo, here I'm using gVim under Windows with my [vim configuration](https://github.com/brookhong/vimfiles).

My `<leader>` key in VIM is `s`, so don't be surprised when you're seeing my
actions started with `s` in normal mode.
And I do have some window operations started with `<Space>`.

Here we go.

The animations are created with [LICEcap](http://www.cockos.com/licecap/)
plus [KeyCastOW](/assets/downloads/keycastow.zip).
Please checkout [the code](https://github.com/brookhong/KeyCastOW).
