67) If 1 (default), your attack speed will be immediately reset to normal upon release of any key assigned to line 33. If you would prefer a delay, set this line to 0, set line 8 to 1, and set line 9 to whatever delay you want.
The above line basically reverts the previous change made to keybinds. You can now choose whether you want a delay or not (upon releasing a key). For safety, line 67 will be enabled by default.
Updating Speeder to version 33 is necessary.
