go is a small shell command for changing directories quickly. Typically you have a set of directories that you work in. Typing out the names of those dirs in full can be tedious. go allows you to give a shortcut name for a directory -- say ko for D:\trentm\main\Apps\Komodo-devel -- and do the following: C:\> go ko D:\trentm\main\Apps\Komodo-devel>and C:\> go ko/test D:\trentm\main\Apps\Komodo-devel\test>These examples are from Windows (in the cmd.exe shell), but go works for Linux, Mac, etc. as well. Think of it as a super cd. See GettingStarted for more details.
