docs: skriv det, der blev bygget, og ret det, der ikke passer længere

To nye sider. Postkasser: at stjerne i Gmail eller flage i iCloud og Fastmail
bliver til opgaver, at hver postkasse hører til den, der forbandt den, at
app-kodeord er noget andet end ens rigtige, og at Office 365 ikke kan nås ad den
vej — sidstnævnte skrevet ned frem for at blive opdaget ved at prøve. Og at logge
ind: kodeord, totrinskode og passkeys, med hvorfor en passkey ikke kan laves på
en bar IP-adresse.

Konfigurationen manglede VERDANDE_SECRET_KEY, som er den, det koster mest ikke at
vide noget om: mister man nøglen, skal postkasserne forbindes forfra. Begrundelsen
står med — det er kopierne, ikke serveren, der er problemet, for de kan hentes
gennem fladen.

Og genvejsafsnittet i quick-add beskrev q, t og u, som ikke findes længere. En
dokumentation, der lover taster, der ikke gør noget, er værre end ingen: man
prøver, der sker intet, og så tror man appen er i stykker.

Bygget med --strict; alle krydshenvisninger rammer.

+It only fires when nothing else has focus — a key pressed at a field, a button or

+Under the field is a line saying what the parser reads: `#` project, `/` section,
+`@` label, `p1` priority, and an example date. It appears while you are typing,
+which is the one moment a placeholder cannot help you.
