Neovim

demicolon.nvim is a plugin that lets you use ;/, to repeat more jumps than just t/T/f/F like diagnostic jumps with ]d/[d and treesitter text-object jumps like ]f/[f to next/previous function.

Now you can also easily make your own custom jumps repeatable with ;/,. For example, I've now made gitsigns.nvim's ]c/[c repeatable out of the box with demicolon.nvim. Here's the implementation if you're curious. For more information see the custom jumps section in the README.
