Describe the feature

When navigating code, navigating using option-arrow command is a big part of the process.
I'm coming from JetBrains' IDEs and having the editor treat _ (underscores) as word separators is a very important part when it comes to languages where snake_case is the syntax.

In JetBrains editors, the setting is called Settings|Editor|Smart keys|Use "CamelHumps" words CamelHump. Which treats names such as thisFeature as two words: this|Feature and this_feature as two words: this|_|feature (| indicating where the cursor stops when navigating with opt-arrow).

Thank you.

Gotcha, so basically you'd like to have a setting which alters the word boundary behavior such that you can do word navigation (alt-left, alt-right) which considers CamelCaseWords or snake_case_words as word boundaries.

Yes, that is correct.
