When the toggle hotkey is pressed ( F1 in this case), the script will play 11.mp3 from the "sounds" folder to inform that the feature is activated. After that, pressing the "H" key will cause you to turn around 180 degrees in game.
The feature can be toggled on/ off using the hotkey (F1 in this case). When toggled off, the action of pressing the "H" key in CSGO will not be replaced by the script, leading to the local player doing nothing.
Change "F1" to your desired toggle hotkey ("X" with "X" representing the key of your choice. For example if you want the toggle key to be the "F" key you replace "F1" with "F"). Change "H" to your desired activation key. ("*~$X" with "X" representing the key of your choice. For example if you want the activation key to be the "F" key you replace "*~$h" with "*~$f")
