All Seven Pashto-Only Letters Are in the Keyboard's Last Row
Unlike Sindhi's extra letters, which are spread across several rows, Pashto's are grouped together at the end of the 5th row: ټ، ډ، ړ، ڼ، ښ، څ، and ځ, right before the Space key. If you're looking for any of these, you don't need to scan the whole layout — check the tail end of the last row first.
One exception worth knowing: ګ (Pashto gaf) is also Pashto-specific — a separate Unicode character from the Urdu/Persian گ, distinguished only by a small ring mark most people miss at a glance — but it sits in the 3rd row with the more widely shared letters, not with the row-5 cluster.
ځ and څ Are Easy to Mix Up
ځ and څ — both in the 5th row, sitting right next to each other — share the same base letter shape and differ only in a small mark above it. They represent different sounds and aren't interchangeable. If a word looks slightly off after you type it, this pair is the first thing worth double-checking before you check anywhere else on the layout.
ښ Works the Same Whether You Pronounce It Sh or Kh
ښ (5th row) is read differently depending on the reader's region — closer to "sh" in some areas, closer to "kh" in others. The keyboard doesn't ask you to pick a dialect: there's one key and one character, and it's correct for readers on either side of that pronunciation difference. Type the word the way it's conventionally spelled, and it will read correctly regardless of how the person reading it pronounces that letter.
Numerals and the Question Mark
The top row uses the Extended Arabic-Indic digit forms (۰۱۲۳۴۵۶۷۸۹) shared with Persian and Urdu digital text, rather than the Western Arabic-Indic forms used in standard Arabic. The row also includes ؟, the Arabic-style question mark — worth knowing if you're used to a layout that only gives you the comma and full stop.
