How can I split a toolbar?

I would like to put my toggle hotkey trigger keys on a separate toolbar that remains visible. The current toolbar has full width. How can I reduce the width of that toolbar and place a new toolbar with two buttons beside it? Is there any help file for how to split / join / position toolbars?

Just create another toolbar and drag the buttons to it. You can have more than one toolbar per row if you want.

If you're toggling toolbars via commands, there's a POS argument to specify where the toolbar should open.

Where can I find a list of arguments so that I know how to use them properly?

Or push F1 in the button editor when on a line which runs the command you want help for.
