Fastuzm for Any weapon is a macro that works with the right mouse button (PCM) and ensures maximum accuracy of entering the sight before firing. 

When using a macro, it is enough to press the PCM button, and the character will immediately enter the sight and make an instant shot. 
For the convenience of users who prefer to hold the PCM for long-term aiming, it is recommended to change the macro settings so that instead of pressing the button, it is required to hold it. 
The advantage of this mode is that if you are already in the sight and waiting for the enemy, when you shoot, there will be no opportunity to accidentally exit the sight and make a shot. 
However, if the «press the button» mode is selected and you are in the sight, then after the shot you will be automatically thrown out of the sight, and then a shot will occur. 
Immediately after performing a fast shot, you will automatically enter the sight again, and to exit it, you will need to release the PCM button. 
If the «hold button» mode is activated, then all the situations described above will not occur, and the macro will work perfectly regardless of the settings.
