# Variables

Syntax: `{<variable_name> [flags] [<attributes>]}`

## Variable Name

The variable name is the name of the variable, for example `fps`, `x` or `ping`. You can read more about these later.

## Global Flags

Global Flag Syntax: `-<flag_name>[=<value>]`

Global flags are flags that can be applied to all variables (to some limits, you can't round a text for instance, that would give you an error).

For example a global flag could be `-uc` which would make the value uppercase.

You can find all global flags at [Flags](/docs/docs/flags.md#available-global-flags).

## Specific Flags

Specific Flags Syntax: `--<attribute_name>[=<attribute_value>]`

Specific variables are unique to the variable, and can only be used on the variables which accepts it. For example, the `key_pressed` variable takes a specific flag called `key`.

{% hint style="info" %}
You can use both global and specific keys, and use multiple of each on the same variable! For example, `{biome -sh-nd-tc}` would give you `Snowy Taiga` instead of `minecraft:snowy_taiga`
{% endhint %}
