The ability to revert a diff hunk was added in Sublime Text 4. You can access it through the Command Palette command “History: Revert Hunk.” For quicker access, you can use a custom NeoVintageous mapping.

I like to map undoing hunks as <leader>hu. This is the mapping used by vim-gitgutter, the popular vim plugin.

let mapleader=,
nnoremap <leader>hu :RevertHunk<CR>

To edit your rc file use the command palette: Open RC File.

To reload your rc file use the command palette: Reload RC File.

Jumping to diffs

You can jump to the next or previous diff with the commands ]c and [c.

Support for jumping to diffs was added in Sublime build 3189. In previous versions you needed Git Gutter.
