+# TIPS & NOTES
+#============================================================
+- Ctrl + o in Insert mode is a powerful way to run one Normal-mode command temporarily.
+- Use “aw”, “iw”, “ab”, “ib”, etc. with operators (e.g., ‘daw’, ‘yib’) for precise text manipulation.
+- The system clipboard is “+” (Windows/macOS/Linux), but some X11 systems also use “*”.
+- When in diff mode, ‘do’ and ‘dp’ are complementary: “get” vs. “put” changes.
