The Roadmap to Completely Replace Emacs's Key System, Part 2.5

By Xah Lee. Date: . Last updated: .

a few months ago, i started to design a keybinding set that completely replaces the entire emacs 1k+ keybinding.

i've been using it for a few months now. I want to publish it nicely, but just haven't got to it.

so, am just pushing it out as its current state, here:

again, i'm pushing out in its current chaotic state, hoping some keyboard hackers will pick it up, in case i never do.

to use it, you need:

here's a bit detail to help along:

there are 2 types of command: fast-repeat command and none-fast-repeat command.

the fast-repeat commands are moving cursor, delete characters, etc, where it makes sense to hold down a key and have it repeat. Typically, in emacs, there are 20 to 30 fast-repeat commands.

vast majority of emacs commands are non-fast-repeat. e.g. open file, switch buffer, dired, shell, calc, …

fast-repeat commands you need a single key or key chord.

fast-repeat commands are also the most frequently used commands, every second or few seconds.

ergoemacs-mode, is a package that solved the fast-repeat commands. (ergoemacs-mode also has a system for non-fast-repeat commands, but isn't designed from the ground up. It's based on converting emacs C-x to non-chord key sequences.)

xah fly keys is my new package that deal with fast-repeat commands. The key choices are mostly compatible with ergoemacs-mode. The major difference is that this is a modal input system, like vi.

that leaves the non-fast-repeat commands, which is basically all commands of emacs C-x keys.

so, the news is, i've now designed a set for this. The key map choice is based on frequency of the command and ease of key position.

If you find a GNU emacs command that by default has a key but is not covered here, it's a bug. (actually, it's 98% complete. there are about 100 commands with keys that is rarely used. (you can see them near the end of the file, as commented out lines. i wasn't sure what/where to do with them yet))

this is new because it's the first time i completely designed entire emacs keys for public use. Before, i was simply using my own keys without regard to other people's use.

addendum: the keys are merged into xah fly keys
