Use Helix for a real small change: navigate a repository, edit several files, search references, run tests, and inspect the diff. Check language-server diagnostics, formatting, clipboard behavior, and the selection-based commands you would use all day.
A modal editor has a learning curve, so separate unfamiliar shortcuts from missing functionality. Keep your previous editor available while testing remote sessions and project-specific tooling. The right decision is whether the full change is faster and safer after practice, not whether opening the first file feels novel.
