Basic Controls and the Inventory screen:
Jump: C
Attack: X (You may attack while jumping or dashing)
Skill: (command) + Z
Dash: Doubletap in the direction you want to dash (→→ or ←←)
Pick up item: X (while over the item)
Equip/Use item: Drag and drop the item into the appropriate slot, or right click to use an item. You may drag items into your hotkey-item slots at the bottom left of the screen - note that each slot counts as a storage space for one item and the item will be removed from your main inventory.
Items are classified in your inventory according to item type. There are four tabs: Equipment, Consumable items, Materials and Quest items. Each of these tabs has 32 slots. You may delete items you do not want by dragging them outside the inventory window. There is also a bar that displays your carrying capacity (weight limit) right to the left of the sort button.
The coin to the left of this bar shows how many continue coins you have left. Below it, you can see how much money you have, and the hand making the V-sign shows your PvP points.
