Here are two buttons, one for including nodes and one for including fields.

You enter a node type and all node names appear in a drop down button.
You enter a textfield name and all fields (which contain a value) appear in the drop down button.

Installation:
-------------
1) Attached archive: Import the buttons via BUEditor's import function and copy the Javascript file to your BUEditors Javascript folder (default: modules/bueditor/library/). 
2) Since per default they are embedded by NodeID, you need both RepTag module + additional tags to make it work:

[#318039]
3) Define the node type and field name for the buttons at bueditor settings. (if you want to have more than one node type/field, create a new button).

Have fun and post bugs if you find some, please. Field button works only with textfields.
