Emacs: Set Default Path for speedbar
speedbar uses the folder of the file that is associated with the current buffer
as the default path. For example, if I open speedbar when
editing ~/.emacs.d/dotEmacs/init.el , it will display files
under ~/.emacs.d/dotEmacs/ . However, I use dired-jump to achieve a similar
functionality, and for me speedbar is a simple project explorer, so I hope it
could open a certain folder once activated.
