vim-ficklefold VS fzf.vim

If you don't get great results, try changing 'foldmethod' (syntax is usually best but indent often works well). If vim doesn't have syntax support for your language, find a plugin that offers it. Even better if it defines 'foldtext' so your methods collapse down into an easy to read outline. I use vim-ficklefold to manage folds and FastFold to prevent syntax folds from making vim slow.

Fuzzy Finder: fzf.vim (for its speed) along with telescope.nvim (for its ecosystem)

And added my keyboard shortcuts.

There are two plugins allowing us to use fzf in Vim: the native fzf plugin directly installed with fzf, and fzf.vim. The second plugin is built on the first one.

You might be interested in installing the fzf-vim plugin [0]. It has a user-defined command :Maps which can be used to search through all keybindings (you can also do this with just :nmap in vim, but the fzf interface is much nicer). It also provides :Commands. This behaves remarkably like VSCode's command palette.

You'll also need https://github.com/junegunn/fzf.vim (which is imo the only vim plugin that's a must).

I do all my file operations from the command line. But to open and search files I use fzf

Regarding plugins , I am using https://github.com/Donaldttt/fuzzyy because it works in windows, unlike https://github.com/junegunn/fzf.vim

There's a :Buffers command in fzf.vim that I use extensively. It opens a fuzzy-find window with all open buffers in a MRU list.

Thanks to fzf.vim and fzf-lua, everything I learned and copied is from them.

they're likely referring to fzf.vim, the vimscript plugin from the original fzf author that wraps around fzf. there's also fzf-lua nowadays.
