## General options syntax
Options have the general format:
> _options_ ::= (`";"` _option_)*
In general, an _option_ can be any string of characters not including control characters (value less than 32) or semicolon. Usually the will have the form of a _named-option_:
_named-option_ ::= _option-name_ `"="` _value_
A terminal must ignore an _option_ whose _option-name_ it doesn't recognize.
**Issue**: Alternative specification: If a terminal doesn't recognize an _option-name_ it should ignore it _and_ any subsequernt options.
**Issue**: Maybe allow _value_ to be a quoted string, with C-style escapes?
## Standard options
`aid=` _value_
> The current _application identifier_.
`click-move=` _value_
> The _value_ can be `line` or other options to be determined later.
> This is a request from the application to the terminal to
> translate clicks in the input area to cursor movement.
