I have been a vim user for many years. During that time I have never seriously tried to switch to another text editor, even with the increased popularity of neovim.

Helix is implemented in Rust and like many modern Rust tools (e.g. rg, fd), feels quick and snappy. Although many of the key bindings are similar, there are significant differences with vim.

• Since text is always selected (e.g. the cursor alone indicates a single character is selected), d will delete one character

There are numerous subtle differences betwen the key bindings of vim and Helix. The transition can be eased with helix-vim, which remaps keys to be closer to vim.
