- add text to multiple lines:
  - highlight multiple lines with Shift+V
  - type `:`: you will see `:'<,'>`
  - type `norm A`: this goes into `norm`al mode and `A`ppends to the end of the line
  - type whatever you want to add
  - example: `:'<,'>norm A;`: adds a `;` to the end
  - you can do the same for the start of a line by using replacing `A` with `I`

- delete inside next parentheses:
  - find next opening parentheses: `f(` (hit `;` for the next location)
  - delete inside parentheses: `di(`
