A: Environment Strings
A.1 Usage
An environment string is a sequence of key letters, sometimes prefixed by a plus (+) or minus (-).
Environment strings can be used with certain commands to configure connections. The keys are added after
the hostname (if one is given) and a colon.
Key letters are not case-sensitive, and no white space is allowed in the environment string. In addition,
commands that oppose previously-configured settings will overwrite the previous setting, even if they
appear on the same command line.
A.1.1 Multiple Strings
More than one string can be entered as part of a single command. Multiple strings do not need to be
separated from each other. For example, you can enter a command that specifies both the desired port
number and that the connection should in Passall mode.

A.2 Available Strings
Note:
In most applications, environment strings are not necessary.
Environment keys must be separated from the hostname, if one is specified, by a colon. Read the following
sections carefully for more details on proper usage of each key.
