ZoomIt is a free software that lets you zoom into parts of your screen, and draw on your screen. This is a really useful feature while you are giving presentations, and need to highlight some section of screen. This also comes handy if yu are preparing some training videos. ZoomIt is completely free, and easy to use.
Whenever I am giving some online presentation by sharing my screen, I always feel a need to be able to quickly zoom some sections of my screen. For example, I might want to quickly zoom into a set of buttons to talk about what each button does. Similarly, I also feel a need to be able to quickly draw on my screen while talking about some new idea or application, to visually explain more clearly what I am talking about.
(Some of the free services that you can use to share your screen online: DimDim, Yugma, Mikogo)
I did not have a solution to do this till now. But thankfully, ZoomIt would let me do exactly that.
ZoomIt makes it extremely simple to zoom sections of your screen. When you start ZoomIt, it keeps running in system tray. You can quickly bring it up by pressing your chosen hotkey combination. This will bring up the zoom window. The zoom window will move with your mouse cursor, so you can quickly zoom any other part of the screen that you want.
ZoomIt lets you specify a separate set of hotkey for Drawing. Pressing that hotkey combination will bring up a pen on screen, and you can quickly draw using your mouse. You can specify pen color and size.
A great feature of ZoomIt is that it even lets you draw on Zoomed window.
I really like ZoomIt for it simplicity, and its usefulness. I am going to be a regular user of it during my presentations.
