new version of ErgoEmacs Keybinding is out again. I'm happy to report that the current maintainer Matthew L Fidler has adopted a idea i suggested. Now, “all” of chorded keys has a non-chorded replacement! You can press them by pressing ▤ Menu key first. Here's the current keys:
("<menu> g" keyboard-quit "Quit")
("<menu> j" ergoemacs-ctl-c "Ctl-c")
("<menu> u" ergoemacs-ctl-c-unchorded "Ctl-c*span")
("<menu> f" ergoemacs-ctl-x "Ctl-x")
("<menu> h" ergoemacs-ctl-h "Ctl-h")
("<menu> y" ergoemacs-ctl-h-unchorded "Ctl-h*")
("<menu> m" ergoemacs-ctl-c-ctl-c "C-c C-c")
("<menu> SPC" set-mark-command "Set Mark")
The keys are position based, and QWERTY layout is used to indicate their position. That means, doesn't matter whether you are using Dvorak, Colemak, Workman, Bépo, …, you can just look at the labels on your keyboard for the right key. The keys may not be final. But Matt is the maintainer now, so, you'd have to ask him, for suggestions or code push. Also, i haven't been keeping up my documentation of it. I hope to fix it down the road. Another new layout support is Persian standard layout, contributed by Shahin Azad. (it also supports Workman layout. and quite a few others now. You can see all layout supported in the menu 〖ErgoEmacs〗)
Matt also created a emacswiki page at http://www.emacswiki.org/emacs/ErgoemacsKeybindings, so you can post there, ask for help, or help make it better. (Matt says that don't use the emacswiki for question, because it's automatically generated from info file.)
for why about the non-chorded keys, you might get a good idea from my notes here: The Roadmap to Completely Replace Emacs's Key System, Part 2
i think this is really great, because for years i've been thinking how to resolve the cua-mode and emacs C-x issue. Now, i think this is the answer. The implementation is simple, and we don't need the complex hack of cua-mode anymore, and the traditional C-x are still there if one wanted, and the whole system is one step more efficient and ergonomic, even beats vi-like modes. (the main issue of vi's modal ways is that you need to constantly switch modes.)
