shortcut to trigge clockbar up

[cityKspicyChicken]

Hello L1cardo, I have already installed Touchswitcher of dock and I can invoke it by click shortcut <option + 9>, but if I would like to invoke clockbar to show me the time and hide the menu bar in the top of the screen so that make most of the 16 inch screen. I am wandering if there is a shortcut for toggle clockbar, the same as for Touchswitcher.

p.s. By Touching the Touchswitcher icon in the Touch Bar, I can change the Add-on to clockbar, but if there are more than 2 add-ons, how can I switch among them easily.

我注意到你的名字是 Xiaoyuan Cai， 如果你是中国人，你可以用汉语描述你的问题。你上面说的我没有太理解。
如果可以的话，能否带上一些照片，便于我理解。
