| `XY` | A special code that may be utilized for placement identification when creating menus or to extend an otherwise empty space in an art file down the screen. |
Predefined MCI codes and other Views can have properties set via `menu.hjson` and further *themed* via `theme.hjson`. See [Themes](themes.md) for more information on this subject.
Often a module will provide custom properties that receive format objects (See **Entry Formatting** below). Custom property formatting can be declared in the `config` block. For example, `browseInfoFormat10`..._N_ (where _N_ is up to 99) in the `file_area_list` module received a fairly extensive format object that contains `{fileName}`, `{estReleaseYear}`, etc.
Various strings can be formatted using a syntax that allows width & precision specifiers, text styling, etc. Depending on the context, various elements can be referenced by `{name}`. Additional text styles can be supplied as well. The syntax is largely modeled after Python's [string format mini language](https://docs.python.org/3/library/string.html#format-specification-mini-language).
### Additional Text Styles
Additional text styles are available for numbers:
| Style | Description |
|-------------------|---------------|
| `sizeWithAbbr` | File size (converted from bytes) with abbreviation such as `1 MB`, `2.2 GB`, `34 KB`, etc. |
| `sizeWithoutAbbr` | Just the file size (converted from bytes) without the abbreviation. For example: 1024 becomes 1. |
| `sizeAbbr` | Just the abbreviation given a file size (converted from bytes) such as `MB` or `GB`. |
| `countWithAbbr` | Count with abbreviation such as `100 K`, `4.3 B`, etc. |
| `countWithoutAbbr` | Just the count |
| `countAbbr` | Just the abbreviation such as `M` for millions. |
#### Examples
Suppose a format object contains the following elements: `userName` and `affils`. We could create a `itemFormat` entry that builds a item to our specifications: `|04{userName!styleFirstLower} |08- |13{affils}`. This may produce a string such as "<fontcolor="red">eVIL cURRENT</font><fontcolor="grey">-</font><fontcolor="magenta">Razor 1911</font>".
Remember that a Python [string format mini language](https://docs.python.org/3/library/string.html#format-specification-mini-language) style syntax is available for widths, alignment, number prevision, etc. as well. A number can be made to be more human readable for example: `{byteSize:,}` may yield "1,123,456".
