Unity keyboard/mouse shortcuts
On MS Windows we can use Super + Arrow to move a window to the right and the left of the screen, maximize, minimize and even move it to another screen. Is there a way to configure this feature on Unity?
Ctrl + Alt + NUMPAD 4 (left edge) Ctrl + Alt + NUMPAD 6 (right edge)
Make sure you are using the NUMPAD cursor keys, not the dedicated ones, if you have those. Otherwise, it'll switch workspaces.
Note that these shortcuts only work on non-maximized windows. Un-maximizing any selected window can be done using
Ctrl + Alt + NUMPAD 5 (center)
List of Unity keyboard shortcuts here in case you haven't seen them.
The script below does exactly as you describe. It can be used on any number of screens. The script is optimized for Unity, but can easily be edited to fit other window managers.
It turned out to be a bit more complicated than I thought, since the script should take into account that the user possibly set the launcher to only appear on the leftmost screen (or not). The targeted positions (and targeted window sizes) should be calculated accordingly.
xdotool and wmctrl - commands. Since these commands can have some "characteristic behaviour" in combination with Unity, there is a possiblility minor changes can be useful on your system. I tested it on two (quite different) systems however, working fine on both.#!/usr/bin/env python3
import subprocess
import sys
# --- set possibly wanted marge (on the right side of the window) below
marge = 0
# --- set set launcher width below (default = 65)
default_launcherwidth = 65
# ---
move = sys.argv[1]
get = lambda cmd: subprocess.check_output(
["/bin/bash", "-c", cmd]).decode("utf-8")
screendata = [l for l in get("xrandr").splitlines() if " connected" in l]
# get the primary screen's position
pr = [l.split() for l in screendata if "primary" in l][0]
i = pr.index("primary"); s = pr[i+1]
primary= [int(s.split("x")[0]), int(s.split("+")[-2])]
# general screen list
screendata = [
[s for s in l.split() if s.count("+") == 2][0] for l in screendata
]
screendata = [
[int(s.split("x")[0]),int(s.split("+")[-2])] for s in screendata
]
screendata.sort(key=lambda x: x[1]); primary = screendata.index(primary)
def launcher_size():
launcherset = get(
"dconf read /org/compiz/profiles/unity/plugins/unityshell/num-launchers"
).strip()
l_size_0 = 65; l_size_1 = l_size_0 if launcherset == "0" else 0
return [l_size_0, l_size_1]
def magnets(index):
l_size = l_sizes[0] if index == primary else l_sizes[1]
screen = screendata[index]
screenwidth = screen[0]; shift = screen[1]
parts = (screenwidth - l_size)/2; virtual_mid = screenwidth - parts + shift
left_trigger = shift + l_size
return [left_trigger, int(virtual_mid), int(parts)]
def find_screen(x_loc):
scr_index = len([scr for scr in screendata if x_loc >= scr[1]])-1
scr_index = scr_index if scr_index >= 0 else 0
screen = screendata[scr_index]
return [scr_index, screen]
def get_active():
active = hex(int(get("xdotool getactivewindow").strip()))
active = active[:2]+(10-len(active))*"0"+active[2:]
x_pos = int([l.split()[2] for l in get("wmctrl -lG").splitlines() \
if l.startswith(active)][0])
return [active, x_pos]
def decide(x_loc, active):
current_scr = find_screen(x_loc)
triggers = magnets(current_scr[0])
width = triggers[2]
index = current_scr[0]
if move == "left":
if x_loc <= triggers[1]:
if x_loc == triggers[0]:
if index != 0:
alter = magnets(index-1)
width = alter[-1]
target = alter[1]
else:
target = triggers[0]
else:
target = triggers[0]
elif x_loc > triggers[1]:
target = triggers[1]
elif move == "right":
if x_loc >= triggers[1]:
if index != len(screendata)-1:
alter = magnets(index+1)
width = alter[-1]
target = alter[0]
else:
target = triggers[1]
elif x_loc < triggers[1]:
target = triggers[1]
subprocess.call([
"wmctrl", "-r", ":ACTIVE:","-b", "remove,maximized_vert,maximized_horz"
])
subprocess.call(["wmctrl", "-ir", active, "-e", "0,"+str(target)+",400,"+\
str(int(width)-marge)+",200"])
subprocess.call([
"wmctrl", "-ir", active, "-b", "toggle,maximized_vert"
])
l_sizes = launcher_size()
w_data = get_active()
active = w_data[0]
x_loc = w_data[1]
decide(x_loc, active)
The scrpt needs both wmctrl and xdotool:
sudo apt-get instal xdotool wmctrl
Copy the script into an empty file, save it as move_window.py
Test- run the script from a terminal window by (repeatedly) the command:
python3 /path/to/move_window.py right
which should move the window through your screens to the rignt, and:
python3 /path/to/move_window.py left
which should move the window through your screens to the left.
If all works fine, add both commands to shortcut keys: choose: System Settings > "Keyboard" > "Shortcuts" > "Custom Shortcuts". Click the "+" and add the commands to two shortcut keys of your choice.
The launcher width is set to 65px (corresponding to icon size 48px + 17px borders, which is the default). If the set width is different, it should be set correctly in the head of the script, as indicated in the section:
# --- set set launcher width below (default = 65)
default_launcherwidth = 65
# ---
In the headsection of the script, there is furthermore a line:
marge = 0
which sets the empty marge at the right side of the moved screen. Change it if you like to another value.
Best Answer
On Unity, you can press Ctrl + Alt + Numpad 1 to move the window to the bottom left of the screen.
You can also use Numpad 4 to move it left, Numpad 7 to move it top left, Numpad 8 to move it top, Numpad 2 to move it bottom, Numpad 9 to move it top right, Numpad 6 to move it right and Numpad 3 to move it bottom right.
I hope this helped you,
