Register

(info)

• a space in memory with an identifier that vim uses to store text
  • analogous to a clipboard
• access register a - "a
  • access register in i mode - <C-r> (instead of ")
• vim has a default register, which is where any deleted or yanked text will be
  • denoted "" - so p is shorthand for ""p
  • this is more like copy/paste
• when writing to a register, lowercase letters will overwrite the register, while uppercase will append to the register
• Sequential register
  • "1 is most recent (or ""), "2 is second most recent, and so on
  • this is only for dd and yy operation
• Yank register
  • "0
• Blackhole register
  • "_ - prepending a command with this will prevent anything from entering a register.
• Clipboard register
  • "+/"* - gives access to the system clipboard
• Expression register
  • "=
  • when fetching contents from the register, we enter command-line moe
  • an exception to the idea that "registers are containers that hold a block of text"
• use :reg to see all registers
  • :reg a b c will show registers a b c
• copy text into register r, then paste it - "ry, "rp
• Yank Register - when yanking, the copied text is placed into the yank register ("0), as well as the default register.
• Delete/yank Register - "-
  • only small delete (ie. no dd)
• when using visual mode to make a selection of text that we will replace with p, the highlighted text will go into the register as the pasted text exits
