── WHAT ARE THE ARROW SYMBOLS?────────────────────────────────────────────────
The four basic arrows → ← ↑ ↓ (U+2190–U+2193) anchor Unicode's Arrows block — over a hundred pointers covering doubles ⇒, diagonals ↗, hooks ↩ and long forms ⟶. The right arrow is the workhorse: mapping A to B in commit messages, changelogs, keyboard-shortcut docs ("File → Save") and this very site's navigation.
Arrows are older than Unicode: they shipped in the original IBM PC character set, which is why the legacy Alt codes Alt+24 through Alt+27 still conjure ↑ ↓ → ← in many Windows apps — a 1981 keyboard trick that refuses to die.
The classics: Alt+24 ↑, Alt+25 ↓, Alt+26 →, Alt+27 ← — typed on the numpad. They date to the original IBM PC character set, so support varies by app; the emoji picker (Win+.) is the modern fallback.
[+] What is the difference between → and ⇒?
Convention: the single arrow → means "goes to / becomes" (functions, navigation, renames), while the double arrow ⇒ means "implies" in logic and math. Mixing them is harmless in chat but noticed in technical writing.
[+] Why does → sometimes render as an emoji?
A few platforms give arrows emoji presentation (a blue box ➡️). That is U+2192 plus an automatic variation selector. Appending U+FE0E forces the plain text glyph, and the long arrow ⟶ is never emojified.
[+] Are arrows ASCII?
No — ASCII improvised with -> and =>, which survive in code to this day (and some editors render them as real arrows with font ligatures). True arrow glyphs start at U+2190.
