In Section *60.3 Delimiters* of the [TikZ-PGF manual](https://www.ctan.org/pkg/pgf) is written: > The <*delimiter*> can be any delimiter that is acceptable to TEX’s `\left` command. Which are all the delimiters acceptable to TEX’s `\left` command?

They are documented in *The TeXBook*: * [0] The 'blank' delimiter `.`. * [1-2] Parentheses `(` – `)` * [3-4] Brackets `[` or `\lbrack` – `]` or `\rbrack` * [5-6] Braces `\{` or `\lbrace` – `\}` or `\lbrace` * [7-8] Floors `\lfloor` – `\rfloor` * [9-10] Ceils `\lceil` – `\rceil` * [11-12] Angles `<` or `\langle` – `>` or `\rangle` * [13-14] Slashes `/` – `\backslash` * [15] Vertical bars `|` or `\vert` * [16] Double vertical bars `\|` or `\Vert` * [17-22] Arrows `\uparrow`, `\Uparrow`, `\downarrow`, `\Downarrow`, `\updownarrow`, `\Updownarrow` * [23-29] Some special things I have never seen anywhere else but in *The TeXBook*: `\arrowvert`, `\Arrowvert`, `\bracevert`, `\lgroup`, `\rgroup`, `\lmoustache`, `\rmoustache`
