Changes

The '''User Interface''', often abbreviated to '''UI''', term for the game controls, buttons, icons, window layout, input types and everything else that players manipulate to control their [[character]] or view to see the relevant [[Statistic|stats]] of characters, [[item]]s, [[monster]]s and everything else in the game.

[[Cast]]ing a [[spell]] or [[skill]] from the 1234 buttons works just like casting it from the mouse button. You could, in theory, play entirely with the 1234 keys, only using the mouse to target. Generally, players put support skills on the 1234 buttons. [[Summon]]ing spells, [[buff]]s, [[debuff]]s, and so forth. Direct attack skills can be mapped there as well; it just takes some practice to get used to casting these with keyboard buttons, instead of (in addition to) the mouse buttons.
