Are you tired of opening inventory every time to start a chainsaw? I have created a handy macro for this. The main condition is that the chainsaw must be in the second slot, otherwise the macro will not work. You can bind it to any key. When the button is pressed, an attempt to start the chainsaw is made only once. If it doesn't start, just press the button again. The recommended resolution is 1080p, DPI is 1600, and the mouse sensitivity in the game in the first and third person is 12.
