[request] Toggle fold

[diegoulloao]

Why there are fold and unfold keymaps instead of just toggle the fold using one keymap?
Otherwise, it would be good to add the possibility for fold/unfold (toggle) as a new entry in the keymap table.

I have the same opinion here

Same, please

Hi, for the time being (where simrat39 is not very active) I'm maintaining a fork where I've implemented this feature and merged some other PRs -- see the default keymap for toggling folds in the readme.

Also do note on the fork status in the readme, feel free to try it if you really want this feature but proceed with caution :)
