Set text boundaries to zero

Hi,

I want to have the simplest window to edit. I switched to web layout, removed toolbars and menus. However, I can’t manage to remove text boundaries. There is a margin where the cursor is shown on screen as you can see in the picture. I want the cursor to appear just at the border, without these margins. Do you know if is it possible to do it?!

LibreOffice simple screen

if you display the ruler, then set the ruler marker all the way to the left it worked for me.
(then just hide the ruler again).

although I am not sure if you wanted a script for that. alternatively just save the file as a template, so you don’t need to do this each time.
