I’m using Neovim with AstroNvim, and the key maps below will be different depending on your setup.

To find and replace a string in multiple files in vim, you can use this workflow:

• Use telescope to find occurrences of the string (<leader>ff)
• Send the results to the quickfix list (C-q)
• Use the cfdo command to replace the string for all occurrences in the quickfix list: cfdo %s/<old-string>/<new-string>/g | write

To open the quickfix list, type <leader>xq.
