For MMORPGs, there are many possibilities for skills, but the key positions on a standard keyboard are actually not enough. Therefore, there are various keyboards on the market that expand the standard keyboard, such as this type of keyboard.Like this:
In fact, Windows has defined F13-F24, although they do not exist on the keyboard, Windows can respond to these signals. However, these keys are not included in the input settings of Unreal Engine, so players cannot use these keys, such as setting skills to these keys. For MMORPGs, the possibility of key combinations is limited, so players are forced to modify input shortcuts such as opening backpacks to increase the available shortcuts. So should Epic consider supporting these keys?
