k95 rgb Problem K95 Macro G

Good afternoon, I tell you that I have a problem, first of all I want to configure an action in the G1 which for example spam to F5 and when I press G1 again I cut the spam, I can not find the key, another problem I have is I want to configure the LSHIFT and W to keep it pressed for the same purpose, when I press G2 to start and when I press it again, I cut the macro and keep the macro pressed, but when I want to cut it I have to finish closing the icon because it does not stop , From already thank you very much.
