Delete within a word stops at substring delimiters such as _ or change in case

[lucasrangit]

Feature Request:
I want to change the only the substring "MACRO" in VS_MACRO_1 to "CODE", by placing the cursor at the second underscore, pressing Ctrl-Backspace, and type "CODE" to get, VS_CODE_1.

Right now, Ctrl-Backspace deletes everything until the word delimiter (e.g. " ", or "/", etc...).

Yes would be nice to have this.

In Sublime, on Mac, Option-Backspace deletes entire words, but Ctrl-Backspace deletes up to the first symbol.

Sublime, first with Option-Backspace, then with Ctrl-Backspace:

This works only after adding _ as a word separator. And that also works in 1.25. Reopening for clarification.

@chrmarti starting with the previous release we have commands for subword navigation and subword deletion. These new commands (improved via the PR from my previous comment), cover the case reported in this issue.

In other words, verification steps:

1. configure the keybinding { "key": "ctrl+alt+backspace", "command": "deleteWordPartLeft", "when": "textInputFocus && !editorReadonly" }
2. have the string VS_MACRO_1
3. press ctrl+alt+backspace
