Can I add a Save As button in the shortcut toolbar?

I've hidden the menu, but every time I need to save a file as another file name or other location . I'll have to go to the menu and look for it. Could we add it to the shortcut toolbar?

When you hide the menu-bar, a menu button appears on the right side of the tool-bar. It shows all the menus when clicked.

That's called "Save As" (in English), and its shortcut is Ctrl+Shift+S by default. The shortcut can be changed in the Preferences dialog.

I've been cautious about adding buttons to the toolbar, because I want to keep it as clean and functional as possible. If a Save-As button was added next to the Save button, they could be easily mistaken for each other and damage UX. Adding a separator between them would clutter the toolbar. Such a situation doesn't exist with menus or shortcuts.

Ctrl+Shift+S is a universal shortcut for Save-As in editors, and all users are familiar with it.
