Collapse File tree

Hi guys,

Have been trying out lazygit and one thing that I found out is that the arrow keys are used for moving around the different panels instead of something like tab and shift-tab.
My main issue (or something I have not found yet) is that the only way you can collapse or de-collapse a directory in the changes is by pressing the enter key on the directory but if I have a lot of changes it is such a hassle to collapse the directory somewhere mid-tree. Am I missing a shortcut or should this maybe have been the arrow-keys?

Thanks, am enjoying it,
