Vim

Some useful things:

• To paste a register into the command area, do CTRL-R and then the register name.
  • This equally works when you’re in insert mode (handy for when you don’t want to enter normal mode just to paste something)
• Useful registers:
  • The default register when you yank is named "
  • Current file path is in register named %
  • Last search expression is in register named /
• To copy registers from one to another (e.g. to copy the name of the file from one buffer and put it elsewhere): :let @a=@b
• To run macros over a bunch of lines, use the norm! command; e.g. to run macro q on a bunch of lines, select the lines in visual mode and hten do :norm! @q
