Dear user,
Sorry about that. Wise HotKey can only create HotKey which consists of Alt/Ctrl + a number/F key, for example, Alt+3, Alt+F8, Ctrl+5, Ctrl+F3, etc.
As for this "when I want to enter the @ sign using the alt+64 keyboard shortcut, the program starts under the shortcut Alt+6 and Alt+4", Did you create a shortcut for Wise HotKey like the following screenshot in this program? If so, you can delete it
