* Document the feature that allows keys from a generic key map to be overridden for specific applications
* Remove mistaken extra lines in README
* Reduce duplication in example/config.yml by using the default/override key feature. It might be possible to further reduce the duplication in the IDEA config, but I cannot do so without knowing the author's intention
Sometimes you want to define a generic key map that is available in all applications, but give specific keys in that map their own definition in specific applications. You can do this by putting the generic map at the bottom of the config, after any specific overrides, as follows.
```yml
# Emacs-style word-forward and word-back
keymap:
- name: override to make libreoffice-writer go to end of word but before final space like emacs
application:
only: libreoffice-writter
remap:
Alt-f: [right, C-right, left]
- name: generic for all apps
remap:
Alt-f: C-right
Alt-b: C-left
```
Note how Alt-f and Alt-b work in all apps, but the definition of Alt-f is slightly different in LibreOffice Writer. When that app is active, the first definition overrides the second definition; but for any other app, only the second definition is found. This is because xremap uses the first matching definition that it finds.
### virtual\_modifiers
You can declare keys that should act like a modifier.
