GNU/Emacs and Gemini

Gemini and Org mode

Improve some default settings and keybinding of this Gemini browser.

Associate gemini, gopher and finger org links with elpher.

Gemini mode

I maintain a little fork of gemini-mode to improve preformatted or quote blocks, and make links active (open either in elpher or edit targetted file).

My fork of gemini-mode.el (HTTPS)
