jwinder emacs config
introduction
getting started
I prefer to clone this repository as $HOME/emacs-config and symlink it to $HOME/.emacs.d
git clone git@github.com:jwinder/emacs-config.git $HOME/emacs-config
ln -s $HOME/emacs-config $HOME/.emacs.dYou can also create symlinks to a private directory or private.org file in a safe place, containing private or personal settings. This works well for irc passwords, tramp helpers, etc.
ln -s /path/to/your/safe/directory $HOME/emacs-config/private # directory of elisp files
ln -s /path/to/your/safe/private.org $HOME/emacs-config/private.org # file containing elisp segmentsNow, start emacs.

- For a global binding, an empty cell or the value \"global\" can be provided in the Scope column.
- When unsetting a keybinding, an empty table cell can be provided instead of nil in the Function column.
