Thanks everyone for the information (and support!) I did not know that Searchlight could search help menus but as I am also a Windows user, that does not help me. I am a VSCode user (and Emacs and Vim) which all have command lines. I find that tools with large numbers of commands (like Affinity) really benefit from this kind of user interface option. I would theorize that since these tools support Undo/Redo, they likely follow the "Command Pattern" (from the Gang of Four for you programmers) so it should not be horrible to offer a search capability because the commands within the system are implemented as more than just functions.
