Configuring Vim and dotfiles

Sat, 13 Apr 2024 18:24:12 +0200

I switched to Neovim some years ago and have really enjoyed working with it ever since.

Flow is one of the main reasons why. The key mappings and frequent use of melodies over chords makes typing a seamless experience: I rarely have to stop thinking to remember some keyboard shortcut. Most key strokes are deeply memorized and require no effort to recall. And when I do struggle to remember some key mapping, Vim is easily customizable so that I can change the key mapping to something that is easier to remember for me. I never had that experience when working in VSCode or PyCharm, even when trying to make full use of the available shortcuts.
