====== Editing pin values ======
To manually edit the value of an input pin, you may either:
  * Double-click the left mouse button on the pin, or;
  * Right-click the mouse on the pin, and select the '//Edit [pin name]//' menu option. 
This will open a standard L3DT variable editor window, which may look something like this:

===== Why can't I edit a pin's value? =====
Some [[plugins:calc:zeograph:userguide:pins:types|pin data types]] cannot be edited manually. These include:
  * 'hvar', which is a memory handle to a variable. 
  * //probably others//.
Also:
  * You cannot manually edit the value of an output pin. Output pin values are set by the parent filter. 
  * You cannot manually edit the value of a connected input pin. Connected input pin values are set by the peer output pin.
