FWIW, shameless publicity stunt: you can also give [Commander plugin](https://plugins.geany.org/commander.html) a spin 😉
The documentation is a bit scarce, and @elextr will rightfully lecture me about it, but basically it allows looking up actions (basically menu entries) and open files by fuzzy matching.
@b4n I've enabled it. I'll let you know if I have any questions. In the meantime, could you write a document here on how to use it? ;)
