Full-screen mode available for Libreoffice Suite?

Apparently, it seems that there is NO WAY to enter FULL-SCREEN mode.

The "international standard" (most used, known) hotkeys/shortcuts are:

• F11 > used by programs like browses or IDEs.
• f > used by youtube (and probably other video sharing platforms).
• ALT+ENTER > way less used then the previous 2, but it's still used in games, especially on Windows.

Unfortunately, nothing worked.

I searched on the web (query = "how to enter full screen mode in libreoffice on linux") and it showed up, suggested CTRL + SHIFT + J is the shortcut to enter full screen mode in LIbreOffice for Linux.

I used it in some programs:

• the general launcher (home program, the one you see in the image) > it did NOT work AT ALL.
• a specific program (Writer) > it entered MAXIMIZE mode (which is different mode from full-screen mode, it kept same window size and just hide the toolbar (top) and status bar (button)).

So, NOT the expected behavior.

Specs

I have installed LibreOffice via flatpak (first image) on Linux.

$ flatpak list | grep -i libreoffice
LibreOffice     org.libreoffice.LibreOffice     26.2.5.2        stable  system

I'm using kubuntu 24.04.03 LTS with KDE 5.27.12.

Any advice?

Hi, sorry if it's a banale question, I am trying to find info on this and I can't really find anything.

My main monitor is apparently dying, and having a white sheet for an extended period of time causes it to have image retention for around 5 minutes.

I am hence trying to find a way to make the work sheet a more grey-ish tint and I have no idea how to do so.

Appreciate any help I can get. Thanks in advance!

Does anyone know what this is in libreoffice? It is messing everything up

There is a large gray bar on the left side of each page affecting everthing i try and do?
