+# onKey
+`onKey(self, event, key)`<br>
+The computercraft event which triggers this method is `key` and `char`.
+
+Here is a example on how to add a onKey event to your frame:
+
+```lua
+local basalt = require("basalt")
+
+local main = basalt.createFrame()
+local subFrame = main:addFrame()
+  :setPosition(3,3)
+  :setSize(18,6)
+
+function openSubFrame(self, event, key)
+  if(key==keys.c)then
+    subFrame:show()
+  end
+end
+main:onKey(openSubFrame)
+```
