I have found this really cool utility that adds drop-down lists to regular textbox control in virtually any program installed on your computer.
Edit Buddy is a small fully configurable program that saves your time and hassle by adding drop-down lists to regular input fields in all programs throughout your system. These lists can remember history of input entered before by user and also can be pre-configured to contain certain set of data.

Picture 2: Edit Buddy shows drop-down list.
The sample dialog box above represents “Find” feature of regular Notepad. Edit Buddy can also attach itself to all standard “Open” and “Save” dialog boxes to store the list of most recently used folders and/or files.
