+# Basalt
+
+## setMouseDragThrottle
+
+Changes the drag throttle of all drag events. Default value is 50ms - which is 0.05s.
+Instead of sending all mouse_drag events to the :onDrag handlers basalt sends every 0.05s (while dragging) the most recent drag event to all
+drag handlers. If you need all drag events - just change the value to 0.
+
+### Parameters
+
+1. `number` A number in miliseconds.
+
+### Usage
+
+```lua
+local basalt = require("basalt")
+basalt.setMouseDragThrottle(0)
+```
