The VSlick alias facility lets you get at files or directories quickly using your specified aliases. The run command lets you quickly start applications, open directories or files. The dock shows you what’s running and acts as a sort of a repository for favourite applications.
Launchbar lets you get at files, folders, urls and applications with the keyboard using easy to remember aliases or mnemonics. Now, using the keyboard I can quickly get to the application I want without having to watch how I get there.
