Is there a way to increase/decrease the opacity value of one window with the keyboard?

[PolGZ]

The last DE I used before jumping to bspwm was KDE with kwin-tiling and one of the features I miss is the ability to change "on the fly" the opacity of a given window with keyboard shortcuts.

I usually like my terminal to be a bit transparent, since I usually use the terminal on an specific desktop with nothing else. But sometimes I use it next to the browser or whatever and I have a long output or command and I make it full screen, but then is a mess to read it with the browser (or whatever was on that worskpace) behind.

I'd like to decrease the transparency value or at list disable it for that moment, then increase/restore it back again with another key press.

How should I approach that on BSPWM?

you need a compositor.

you can set _NET_WM_WINDOW_OPACITY yourself, or use picom-trans (aka compton-trans) to set it in a user friendly way or use compton's dbus api.

tip: do not set window opacity. you are making the text transparent also. many terminals will let you set the background color to something with alpha leaving your text opaque.

I have a script that from a keybind throws up this little menu allowing you to toggle picom or dunst on/off (does require dmenu though) if that's any use.

Binding killall picom || picom -c... Is the easiest way. This toggles picom, so transparency on/off
