The menu path is view/zoom/zoom/columns/
LibreOffice and “column” brings up references for Calc
.
I want to easily toggle by keystroke between 1,2,3 columns in a WRITER document.
I don’t see a way of setting a key through the shortcut editor so I will have to write a macro I suppose. Where can I find a close example of this macro, or a close enough page in the API documentation.
