I know how to minimize/hide all windows in Cosmic Cuttlefish/GNOME Shell using SUPER+D, but I would like to be able to quickly minimize only all windows for a single application (say the one that currently has cursor focus). For example, I would like to minimize all LibreOffice documents, or all Terminal windows.

I am not quite seeing or recognizing a way to do this in Settings > Devices > Keyboard. Is this possible?

OK, just a quick one for fun :)

Minimize windows of currently active application

You could use a stripped-down/edited version of this script, which comes with a default Ubuntu Budgie install.
While the original script toggles the desktop, the edited one below minimizes all windows, on current workspace, of the currently active WM_CLASS.

The script, how to use

• 
  

  Make sure you have both xdotool and wmctrl installed:

  
  
  

  sudo apt install wmctrl xdotool
  

  
  


• Copy the script below into an empty file, save it as minimize_current.py
  


• 
  

  Create a keyboard shortcut to run the script and you're done :). Use the command:

  
  
  

  python3 /path/to/minimize_current.py
  

  
  

The script

#!/usr/bin/env python3
import subprocess

ignore = [
 "= _NET_WM_WINDOW_TYPE_DOCK",
 "= _NET_WM_WINDOW_TYPE_DESKTOP",
]


def get(cmd):
 return subprocess.check_output(cmd).decode("utf-8").strip()


def get_currws():
 return [l.split()[0] for l in get(
 ["wmctrl", "-d"]).splitlines() if "*" in l][0]


def get_valid(w_id):
 # see if the window is a valid one (type)
 w_data = get(["xprop", "-id", w_id])
 if w_data:
 return True if not any([t in w_data for t in ignore]) else False
 else:
 return False

def get_wmclass(w_id):
 return get(["xprop", "-id", w_id, "WM_CLASS"])


def get_state(w_id):
 return "window state: Iconic" in get(["xprop", "-id", w_id, "WM_STATE"])


currws = get_currws()
allwinsdata = [w.split() for w in get(["wmctrl", "-l"]).splitlines()]
winsoncurr = [w[0] for w in allwinsdata if w[1] == currws]

active_w = get(["xdotool", "getactivewindow"])
activeclass = get_wmclass(active_w) 
relevant = [w for w in winsoncurr if get_valid(w)]


# windows on current workspace, normal state
tominimize = [
 w for w in relevant if all(
 [not get_state(w), get_wmclass(w) == activeclass]
 )
]

for w in tominimize:
 subprocess.Popen(["xdotool", "windowminimize", w])

Note

Note that xdotool nor wmctrl, as used in this script, will work on Wayland.

This is not a keyboard shortcut, but another way to minimise all windows of an application. You can enable 'minimise on click' in Ubuntu dock. Then once you click an application icon in the dock, it would minimise all windows (or raise, if they're already minimised) of that application.

To enable this option, run the following command in Terminal:

gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize'

(Reference: How do I enable 'minimize on click' on Ubuntu dock in Ubuntu 17.10 and later?)
