I made a small useful program; I need to have hot keys in it, that is, I put Button1 so that when I click on it, the program displays a message. But I want, when she was in the tray and I pressed, for example, Ctrl + A , then this message was displayed.

@ karmadro4 you have already suggested the WinApi function for implementation, I’ll just clarify:

RegisterHotKey(handle, 0, MOD_CONTROL, ord('A'));

    I understand correctly that the handle is the application identifier? - Costantino Rupert

    @CostantinoRupert handle is the window handle ( HWND ) to which the window message for pressing a hot key will be sent. In your case, this will most likely be the handle of the main form. - kot-da-vinci
