Out of these, the AF Lock, AE Lock, Exposure Compensation and Display on/off cannot be found on the normal menu and thus are only available when set as one of the shortcuts. Unfortunately, most of the functions can be set only before recording and are thus only useful for taking still photos rather than videos. Nevertheless, it is better than not having any manual settings at all. Once recording has started, you cannot make any changes with these shortcuts exception for the AF Lock and the AE Lock. These two can be toggled on and off individually or in combination while recording.
