Focus Tools

Lectures on IT disciplines (and not only) are often accompanied by a presentation and demonstration of practical actions, for example, in some development environment.
There are free tools to improve the efficiency of information transfer. Also, these tools are indispensable for recording screencasts, allowing you to attract the attention of viewers to the necessary details.

Zoomit

Utility from Mark Russinovich, which is part of the Sysinternals Suite.
Allows:

• increase the area of ​​the screen at the location of the mouse cursor (Ctrl + 1, for Windows Vista and higher LiveZoom is available: Ctrl + 4)
• draw "by hand" (mouse click in zoom mode or Ctrl + 2), straight lines (Shift), rectangles (Ctrl-Shift), ellipses (Tab) and arrows (Shift + Ctrl)
• clear screen - fill with white (w) or black (k) color
• copy the enlarged / drawn image to the clipboard (Ctrl-C) or save to a file (Ctrl-S)
• print text (t in drawing mode), unfortunately, only in Latin

Attention! The utility is addictive :)

Keyjedi

The purpose of the utility is to display the pressed key combinations in a small window. In order to convey all the charms, for example, the Visual Studio editor - that’s it. To work, the .NET Framework is required.

If you use any other lecture utilities (when recording screencasts), please share this information in the comments.
