In Unicode, 001B, 001D, 001C are defined as control characters, without
defining their semantics and usage; see
Are you sure that the keys actually send these codes? Names like "ESC",
"GS", and "FS" that may be used in key caps do not necessarily imply that a
particular code is generated.
Typically, for example, 001B is used in applications to create low-level
"escape sequences", consisting of 001B (ESC) and a few normal characters, so
that the escape sequence as a whole has some control function.
