 ### Keyboard shortcuts for TST's custom functions, for example, [toggle show/hide of the tab bar](https://github.com/piroor/treestyletab/issues/156), [close a tree](https://github.com/piroor/treestyletab/issues/274), [operations to modify tree](https://github.com/piroor/treestyletab/issues/772), [moving focus](https://github.com/piroor/treestyletab/issues/836), and so on
 
-Firefox already have [very large number of keyboard shortcuts](https://support.mozilla.org/kb/keyboard-shortcuts-perform-firefox-tasks-quickly), and other addons also provide their own keyboard shortcuts, I cannot find out safe combinations for my features. So I gave up and decided to provide only [APIs for other addons](http://piro.sakura.ne.jp/xul/_treestyletab.html.en#api). Please use generic addons to customize keyboard shortcuts which can define custom actions based on scripts. Sorry.

Is there any keyboard shortcut to show/hide the navigation toolbar?
