A feature I want in Gnome

There is a feature that I want to be in gnome. I think it needs to be at the GTK level but I have no clue. I started to look into it but I don't know what to call it. The feature I want is something you can do in MS Windows. If you have a window open that has a list you can select a file (or directory or any value in the list) and start typing the one you want. The list will then refocus to the location. Example: I have a list of 500 directories. I know there is a directory in there call "orange" so I click the first directory named "apple" and I start typing "ora" now the list has refocused on orange I hit enter and use this value.
