ISO or ANSI?
Keychron K4C3 (96%) is an ANSI keyboard. The three things a typist notices: the Enter key is a wide horizontal bar on the home row, the left Shift is a full 2.25u wide with no extra key beside it, and the backslash key sits directly above Enter. The right little finger reaches Enter with a short lateral move from the home row, and the left little finger has a wide target for Shift.
Where the symbols sit
These are the keycap legends on Keychron K4C3 (96%) for the characters typists reach for most, taken from the layout file. A symbol printed on a keycap with another legend is reached with Shift or the third-level modifier (AltGr on Windows, Option on Mac), depending on the operating system's layout.
On a US ANSI keyboard @ is Shift+2, the double quote is Shift+apostrophe and # is Shift+3, which is what most typing tutorials assume.
