I see there's some recognition of log - does that need a XML file?

There is a bit of a hacky backend python list that names a couple of
auto-bracketing functions, but being consistent in using XML rather than
that is likely a better plan. It dates from pre-XML days.

Alt+s will give a square root (it's a bit tricky for writing in XML due to
the overbar and continual scaling so is defined in the python code), but if
it's renamed to 'sqrt' from 'square_root', then anyone entering "s q r t
Ctrl+(" will see the text morph into a root symbol. At present it works if
you do "$ s q u a r e _ r o o t Ctrl+(" ($ allowing verbatim entry to
circumvent that pesky underscore)

Multiple arguments can be comma-separated.

Have a look at

As we've overridden the sin function, try 'z e t a' instead. You can even
define your own :)

However, as noted before, this only really works optimally for functions
where we want permanent brackets and an ASCII name such as, I suppose,
'apart',
