What means
It is a historical arrow symbol from the Smalltalk-78 system font. Unlike the familiar rightwards arrow with hook (), whose tail starts above the line and curves down into a shaft, carries its hook underneath a straight horizontal shaft. In diagrams, technical notes, or code, it points rightward to mark a step, link, or directional relation while keeping a distinct silhouette from a plain arrow.
The symbol comes from Smalltalk, the influential programming language and graphical computing environment created at the Xerox PARC research lab in the 1970s. A character chart recovered from a prototype Macintosh system disk preserved inside the built-in Smalltalk-78 system typeface. When historians and engineers proposed encoding these legacy characters in 2021 so old source files and manuals could be stored as plain text, they noted that it corresponded loosely to and was rarely used even by Smalltalk specialists and hobbyists.

1Why does show up as a blank box on my screen?
Yes, many devices still lack a glyph for it. Because it was added in 2024 for historical computing compatibility, only updated system and math fonts include it; for everyday notes or replies, use instead.
