# Drill 1 — Stop using the mouse to open files
# ============================================================

#
# ANSWER: cursor on the variable, then Ctrl+D repeatedly to add the next match;

# For project-wide renames, use F2 (Rename Symbol) which understands scope.

# ============================================================
# Drill 3 — Format-on-save with import sort
# ============================================================
# Make every save format the file + sort imports.
#
# ANSWER: settings.json
# {
#   "editor.formatOnSave": true,
#   "editor.codeActionsOnSave": { "source.organizeImports": "explicit" }
# }
# Pair with prettier / black / gofmt / dotnet format as the default formatter.

#     "command": "npm test -- --watch",
#     "presentation": { "reveal": "always", "panel": "dedicated" },

# Bring your snippets, keybindings, and theme to any machine you sign in on.
