I said,
have parentheses (acos(x)), you need Prefix Mode enabled
Sorry; something felt odd about that, so I did more experimenting. If you followed that advice, and had a third function defined multiarg, which would be used like multiarg(a, b, c) in your code, only the multiarg(a, would be highlighted, which would be just weird. The right way to handle parentheses: turn off the Prefix Mode (don’t need it anymore); go to the Operators & Delimiters; here, you have two choices:
if you want the parens highlighted, but the stuff between not highlighted, then put ( and ) inside the
Operators 1 box (space-separated list). It would then render like the following (where I chose green as the style):

See that the function names are red, the parens are green, and the args are default (black)
if you want the parens and the stuff between highlighted instead, then choose an unused
Delimiter # style (I chose #1 and set it to Blue), with
Open = ( and
Close = ). This will show up as:

See that the function name is still red, the parens and arguments and commas are blue.
The Prefix Mode setting would allow you to write something like open in the list, and every function that started with open, like openFile, openDoor, and openSesame would all be highlighted with that one entry of open.
