There are no commands for selecting symbol fonts. Instead, these are
selected indirectly through symbol commands like |&oplus#oplus;|.
Section~#Sec:math.commands#291> explains how to define symbol commands.

Each math alphabet is a command which can only be used inside math
mode. For example, |#math81#x + #tex2html_wrap_inline1736# + #tex2html_wrap_inline1737#| produces #math82#x + #tex2html_wrap_inline1739# + #tex2html_wrap_inline1740#.

| |
This command selects a math version; it can only be used outside math
mode. For example, || is defined to be | |.
