Some outline commands
You can use Leo as fairly typical outliner. Click the expansion box of nodes to
show and hide their children.
你可以將 Leo 完全作為一個普通的 outliner 。
點擊節點的擴展盒子來顯示隱藏它們的子節點。
Play around with some of the commands from the Outline menu or from the
minibuffer. The keyboard shortcut and minibuffer key sequence appear in
parentheses. Note: as usual, you can use tab completion in the minibuffer.
你可以從 outline 菜單或者 minibuffer 中玩弄一些命令。

注意 ：和普通的一樣，在 minibuffer 中你可以使用 tab 進行補全。

Please experiment with Leo’s outline now. Move around the tree and
expand/collapse nodes by pressing Alt + arrow keys. This also moves the focus to
tree, so, after pressing Alt + arrow, you can move around by using arrow keys
alone. Return the focus to the body control by pressing Enter.
請現在就試試 Leo 的 outline 。
通過 Alt + 箭頭在樹中上下移動，展開閉合節點。
這也移動了焦點，所以，在按了 Alt + 箭頭后，
你可以直接用方向鍵了。
按 Enter 可以把焦點移回 body 中。
