Is there any way by which I can disable the textbox?
Case study: say I have to locate a directory called "xyz". I type "xyz", and the browser will guide me to xyz directory, but I realise I also have to check in directory "abc", then I have to press escape, or backspace delete and search again for "abc". In Kubuntu, I simply have to type "abc" after a gap of say a second. That is very handy. I believe this can be achieved without a search box. Please tell me how.
The timeout does exists. By default 5 seconds after you type anything, the search box will vanish.
Unfortunately, as with too many Gnome variables, this timeout is hard-coded into Nautilus so there's no easy way to fix this. The only way I know of is downloading the source, editing it and recompiling Nautilus.
Those instructions aren't hard to follow and should work.
To default Breadcrumbs view in Nautilus open gconf-editor, go to apps -> nautilus -> preferences and untick always_use_location_entry:
