How to collapse vertical tab bar with a shortcut?

[BarbzYHOOL]

Hello, in 1.14, I pressed Ctrl+B to hide the sidebar containing the vertical tabs, but now it displays the bookmark sidebar instead
SO how do I hide the vertical tabs bar easily?
The setting "Collapse Vertical Tab Bar" in about:preferences is not the same feature

Yes you can using Custom Actions feature:

Example, collapsing Tab Toolbar: https://i.imgur.com/bTaefgt.gif

First, go to Customizable shortcuts and change Custom Action 1 hotkey to F1 and Restart.

Go to about:config and change value of floorp.custom.shortcutkeysAndActions.customAction1
to
var toggletarget = 'TabsToolbar'; if (document.getElementById(toggletarget).style.display == 'none') { document.getElementById(toggletarget).style.display = 'unset'; } else { document.getElementById(toggletarget).style.display = 'none' }

For Vertical Tab, you might need to change something to make it work, mostly CSS so you can easily figure out.
