term::ansi::code::ctrl - ANSI control sequences
This package provides symbolic names for the ANSI control sequences. For each sequence a single command is provided which returns the sequence as its result. None of the commands of this package write to a channel; that is handled by higher level packages, like term::ansi::send.
This command is for introspection. It returns as its result a list containing the names of all attribute commands.
This command imports some or all attribute commands into the namespace ns. This is by default the namespace ctrl. Note that this is relative namespace name, placing the imported command into a child of the current namespace. By default all commands are imported, this can howver be restricted by listing the names of the wanted commands after the namespace argument.

Optimize character graphics. The generator commands above create way to many superfluous commands shifting into and out of the graphics mode. This command removes all shifts which are not needed. To this end it also knows which characters will look the same in both modes, to handle strings created outside of this package.
Clear screen. In essence a sequence of CursorHome + EraseDown.
Initialize default and alternate fonts to ASCII and box graphics.
Format the block of text for display at the specified location.
