### Limitations

- Only runs in [lbForth](http://github.com/larsbrinkhoff/lbForth).

- It's a block editor, i.e. it's fixed to 16 lines by 64 characters.

### Installation

- Either load it into a running Forth (which the `fmacs.sh` script does),

- Or build a standalone executable with `make`.

### Key bindings

- `M-:` - Evaluate a Forth expression.

- `M-x` - Execute extended command.

- `C-f`, `C-b`, `C-p`, `C-n` - Cursor movement.

- `M-f`, `M-b` - Move forward/backward by word.

- `C-a`, `C-e` - Go to beginning/end of line.

- `M-<`, `M->` - Go to beginning/end of buffer.

- `C-d`, `DEL` - Delete character to the right/left.

- `M-w` - Copy region to kill ring.

- `M-d`, `M-DEL` - Delete word and copy to kill ring.

- `C-y` - Insert text from kill ring.

- `C-j`, `C-m` - Stub; does not break line.

- `C-x C-f` - Stub; does not load file.

- `C-h` - Stub; provide a helpful message.

- `C-x u`, `C-_` - Stub; does not undo.

- `C-q` - Quoted insert.

- `C-g` - Quit.

- `C-@`, `C-SPC` - Set mark.

- `C-x C-x` - Exchange point and mark.

- `C-z` - Return to Forth.  Type `fmacs` to get back to Fmacs.

- `C-x C-c` - Exit Forth.
