emacs: efficient ways of going into a directory
dired-jump, when in dired, it'll go up a directory. Very cool. Because, normally you have to press ^. But, if you've given a easier key to dired-jump than that, then you just press the dired jump key instead!
note: you should never need to call dired directly. Either use dired-jump, or use find-file. (be sure to have ido on, and when in ido-find-file, press 【Ctrl+d】 to go into dir.)
i haven't called dired command for about 6 years. First, i noticed that find-file will do equivalent when your path is a dir. This way, you don't need another key squatting a key spot. Just give a simple key for find-file. (in ergoemacs-mode, the find-file has key 【Ctrl+o】) Then, ido improves the find-file situation by having automated path completion, so that saves you much key strokes. Then, dired-jump replaced other methods to go into dired more than 50% of the time.
