There are no commands for selecting symbol fonts. Instead, these are
selected indirectly through symbol commands like |&oplus#oplus;|.
Section~#Sec:math.commands#293> explains how to define symbol commands.

Each math alphabet is a command which can only be used inside math
mode. For example, |#math87#x + #tex2html_wrap_inline1808# + #tex2html_wrap_inline1809#| produces #math88#x + #tex2html_wrap_inline1811# + #tex2html_wrap_inline1812#.
<#307#>decl<#307#>
| |
This command selects a math version; it can only be used outside math
mode. For example, || is defined to be | |.
