IDEs are wonderful for many things. But I dislike how they make me use a GUI for something I can do faster typing in a command line. For example, opening a known specific file. If I know the name of a file, from the command line I can just type the name of my editor and the filename. With tab-completion I can accomplish this very quickly in a reliable amount of time. No searching through output or moving my fingers off the keyboard.

Is there a way in Eclipse to open a known file simply by typing its path+filename? Maybe through a plugin?

The "Open Resource" shortcut (ctrl-shift-R) is almost it, but it only lets you type the name of the file, not the path. If you have several files of the same name in different directories, you must again hunt with the mouse for what you want.
