pushd [DIRECTORY]
The pushd function adds DIRECTORY to the top of the directory stack and makes it the current working directory. popd will pop it off and return to the original directory.
Without arguments, it exchanges the top two directories in the stack.
pushd +NUMBER rotates the stack counter-clockwise i.e. from bottom to top
pushd -NUMBER rotates clockwise i.e. top to bottom.
See also dirs to print the stack and dirs -c to clear it.
You may be interested in the cdh command which provides a more intuitive way to navigate to recently visited directories.
