Subword navigation functionality?

[gromul]

I'm running {{ CudaText 1.178.0.0, win64-x86_64-win32, fpc 3.2.3 }} and looking for the subword navigation option, e.g. for abc_def or abcDef etc.
Is there are a core feature or a plugin for this? My search didn't find any relevant hits.
If this doesn't exist yet, I'd like to tackle coding a plugin for this.

Yes, CudaExt plugin commands:

Jump: Left into CamelCase/snake_case
Jump: Right into CamelCase/snake_case

It works, thanks!
