Smack can record keystrokes, mouse clicks and movements and playback under three types of speed (High-Normal-Low). with Normal speed keystrokes and mouse clicks are played back as they recorded exactly.with high speed keystrokes, mouse movements and clicks are played back with no delaying time between your event.with low speed keystrokes, mouse movements and clicks are played back with delaying time between your event but more than the normal.

Smack can also generate an Executable Macro file , it means that you can choose any macro you had saved before and simply click "Export to Exe" command button to generate an Executable file for the macro with *.exe extension so it can be run without Smack , just need the vb runtime installed.
