How do I set a hotkey to a specific layout?

I want to be able to toggle VerticalTile on a workspace, but my internet foo is weak today.

key([mod], "o", lazy.layout.VerticalTile(), desc="Tile Vertically"),

Doesn’t work - what will?

Still struggling with this, I found:

qtile cmd-obj -o cmd -f to_layout_index

Which needs an argument, the format of which I cannot work out. It is the index from self.layouts, officially stumped :smiley:
