1. Summary

As the name of the program says, this program let you move mouse cursor one pixel at a time with a keyboard stroke.

Have you ever struggled to move your mouse cursor exactly by one pixel while you were selecting a rectangular region of a picture, or when you were drawing a precisely horizontal or vertical line in a drawing tool? Mouse is a great device to move your cursor roughly close to the point where you want to click. But, itfs no good for precisely pin-pointing an exact coordinate.

I had enough of such experiences and decided to make a tool that I can move my mouse cursor one pixel at a time with a keyboard stroke.

It may be convenient if you put a shortcut to this program in the startup folder. You can do it from the installer.

<< This program is very useful in this situation. >>

The following picture is taken after pressing Alt+PrintScreen to capture a screenshot of a window and then pasting it to the Paint Brush.  Let's say you need to cut out exactly inside the white frame.  One way of doing it is first magnifying the view and then selecting the area.  But, if you do it many times, you may be tired of magnifying and scrolling the picture to pin point an exact pixel on the picture.  The other way of doing it is moving mouse very diligently and carefully to select exact region on the picture without magnifying the view.  But, the problem of this method is it is so difficult to move mouse one pixel at a time.  Unless you are using an expensive professional-grade mouse (if such a mouse exists), your mouse cursor may move 2 or 3 pixels easily when you move your mouse just a little bit.

If you are running this program, you can first move your mouse cursor close to a corner of the picture, and ....

then hold your mouse, and use keyboard to guide your mouse cursor to your target pixel precisely.

Then you click on the left button and this time move your mouse cursor close to the opposite corner, and ....

then use keyboard to move your mouse cursor to the target pixel while you keep the left button down.

Now you can release your left button, and cut and paste the selected region to a new bitmap.

You are able to cut out precisely inside the white frame.  I cannot give you quantitative measurement on how quicker it is compared to magnify-and-select method.  But, to me, it is hell easier!

2. Install

- By Installer :  Double click on setup.exe and follow the instruction. During the installation, the installer will propmt you for if you want to put an icon in the startup folder. If you choose yes, the program will automatically start when you log on for the next time.

- Manual Installation : Rename setup.exe to setup.zip. You can then open setup.zip just like an ordinary zip file. Copy YsMoveMouseOnePixelAtATime.exe and YsMoveMouseOnePixelAtATime.dll to where you want to install. Double click on YsMoveMouseOnePixelAtATime.exe to start the program.

3. How to use

When the program is in the taskbar, by default, you can move your mouse cursor by pressing Right Windows key + one of the Arrow keys.

By clicking on the icon in the taskbar, you can open the configuration dialog in which you can customize the key combination. The choices are:

  • Right Windows + Arrow keys
  • Right Windows + Control + Arrow keys
  • Control + Alt + Arrow keys
  • Shift + Control + Arrow keys
  • Numeric Pad 1,2,3,4,6,7,8,9 keys

I personally rarely use numeric pad. So, I usually assign numeric pad for this program.

I have tested this program on Windows XP and Windows 7. But, some key combination may not work in specific environment. In such a case, please choose another combination.
