+## Item Macros
 
+Currently there are two built-in item macros, that allow rolling the associated skill check or damage roll for a weapon.  Dragging a weapon (try clicking on 'Armor Piercing' to avoid rolling) onto the macro bar results in a macro like this that will roll damage:
+
+```javascript
+game.deltagreen.rollItemMacro("Combat Dagger");
+```
+

+
+You can get a macro that rolls the appropriate skill check instead however with this command:
+
+```javascript
+game.deltagreen.rollItemSkillCheckMacro("Combat Dagger");
+```
+Note that both of these macros search **the currently selected token** for the first instance of an item matching the indicated name passed to the function.
