We have a fairly large application which includes a ton of comboboxes whose Style property is set to 2 ("Dropdown List"). Now I have a new field for which I think the best user interface is a Style 1 ("Dropdown Combo") combobox. This combobox will have a few "standard" entries, but the user will also be able to type their own entry.

My concern is that our users (many of whom are computer newbies), not used to being able to type in a combobox, might choose one of the "standard" entries rather than typing something more accurate when appropriate. One application I saw used blue "elephant ears" (something like parentheses which were colored in) around the combobox control to differentiate this combobox from others. Another option is a tooltip that says (essentially), "Select an option or type your own!"

Does anyone have any other ideas on how to do this?
