Can I rebind <left>/<right> to collapse/expand folders?

[jakst]

I'd prefer it if <left>/<right> worked like in the VSCode file tree, where it collapses/expands the nearest parent folder. I don't find it intuitive to use the arrow keys for panel navigation, as the panels are vertical while the keys indicate horizontal actions. Also panels can also be navigated with both <tab>/<shift+tab> and number keys.

Is it possible to override keybindings for this? It doesn't seem possible from my interpretation of the docs, but I'd love to be wrong (or have it implemented 😅)

This is not currently possible. You can unbind <left>/<right> from the panel navigation with

keybinding:
  universal:
    prevBlock: <disabled>
    nextBlock: <disabled>

But this doesn't help, because the key to expand/collapse the current directory is the generic goInto (bound to enter by default), so you can't map this to right without affecting all other things that you can go into. (This actually sounds like we should fix this, and add a proper keybinding for expanding/collapsing folders. But this still wouldn't help unless we actually have separate commands for expanding and collapsing, and enable/disable those based on the state of the selected item). Also the functionality of collapsing the nearest parent folder is simply not available at all yet in lazygit. That's also tricky to add, because currently expanding/collapsing is only available when a directory is selected.

So I understand the wish, but it's tricky to do. I feel that this would need keybindings that are not just simple mappings, but have logic (conditionals). Maybe that would be a case for #4753.
