Normal Mode:

• In normal mode one can use the regular qwerty-keys to perform common commands:
• • Move around
  • Cut or copy text to the registers
  • Manipulate text programmatically

Command-line mode:

• ":"
• • Once ":" is pressed in normal mode, one can enter the so-called "ex" commands at the command-line.
  • This allows saving the file "w", quitting "q" or "q!", substituting text "s///", etc.
  • Some of these commands will be covered in more detail later on.
