I started using vim seriously a few years ago after I graduated from university. At the time, I wanted a consistent experience between my dev environment at home and at work so I decided to give vim a try. It’s been pretty stable for work and my projects, so I wanted to share my configs and workflow for those interested in playing around with vim.

I’m currently using nvim but this setup should work with regular vim as well. I decided not to go down the lua route just to keep my configuration interchangeable between nvim and vim. I may play around with lua in the future but for now I like to keep things simple.

Useful Hotkeys

One of the benefits of using vim is the hotkey system. Here are some of my favorite hotkeys.

Normal mode

  • g + d - Jump into the definition
  • ctrl + o - go back
    • Useful if you used g + d to jump into a new file. You can use this hotkey to go back to the last file.
  • tab - go forward
    • If you used ctrl + o to go back you can use tab to go forward.
  • ctrl + e - Open NERDtree and focus on it
  • \ + f - Formats the file
  • shift + k - Shows the documentation for the hovered code
  • \ + r + n - Renames the hovered variable/function
  • ctrl + w + v - Creates a vertical split with the same file
  • ctrl + w + s - Creates a horizontal split with the same file
  • g + t - Next tab
  • g + T - Previous tab

Visual Mode

  • ctrl + v - Visual block
  • shift + i - Edit multiple lines

My Plugins

I try to avoid bloating my setup so I only have a few plugins installed.

The .vimrc

Here’s my vim config with some themeing settings removed. If you’re interested in seeing the full configuration you can find it on my github.
