1. copy the contents inside of all-keybindings-telescope-picker.lua and add it to your init.lua
2. you can add common_keybindings.lua into your lua/ folder under your nvim config dir, or to get a (possibly) more updated version you can run the following commands to parse `:h index" yourself

• open nvim in whatever directory you want to create an index.txt in: nvim .
• run :h index to open the help window followed by :w! index.txt to write the current buffer to index.txt
• run python3 index_txt_parser.py to compile a new common_keybindings.lua
• perform step 1 (adding the the picker code to your init.lua) and step 2 (adding the new common_keybindings.lua to your nvim config lua/ folder)

Note: some keybindings might be missing, but hopefully not any very common ones. I think the parser has some issues parsing lines that don't have a tag, which i might fix someday.
