    • When searching with /, you can toggle case sensitivity with \c and \C. For example, /search\c performs a case-insensitive search.
  • Repeat Last Search:

    • Press n to repeat the last search forward or N to repeat it backward.
  • Navigate by Word:

    • Move between words quickly by pressing w to move forward or b to move backward.
  • Delete to End of Line:

    • In Normal Mode, use D to delete from the cursor position to the end of the line.

    • Use g- and g+ in Normal Mode to navigate backward and forward through the undo tree.
