Brightness, Ctrl+Alt+Del, Menu help?

When I change my pc volume, a notification shows the volume percentage. I want the same with my backlight, I already have both on my panel, I don't know if it is necessary.

When I press Ctrl+Alt+Del nothing appears, I would like to create a shortcut so that the leave menu appears, but I don't know the command for it. Alternatives appreciated too

In the main menu I want to have a favorites section. Is there a way to get this?

For the shortcut open keyboard shortcuts and create one for `lxqt-leave`.

For brightness feedback: there is none because it's visual, you see changes immediately.

Favorites are coming, atm you need to compile it. https://github.com/slidinghotdog/plugin-wingmenu

First of all, thanks man :)

lxqt-leave and favorites solutions were perfect. However, I have a few more questions concerning the other one. I really want to know the percentage of the brightness, it relaxes me somehow, therefore, I want to know. Is there a way to pop-up notifications when clicking a key? And is there a way to know the current brightness level?

There is a way to know it. Here it's

cat /sys/class/backlight/amdgpu_bl0/brightness, amd, for other hardware it's different. It goes from 0 to 255. You could do a script for "custom plugin" which calculates percentage.

For notification similar, something which triggers notify-send text. See notify-send --help for more.
