i can retrieve the list of custom key bindings by:

gsettings get org.gnome.settings-daemon.plugins.media-keys custom-keybindings

which return something like: 

['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/', '/org/gnome/settings-daemon/plugins/media keys/custom-keybindings/custom1/', '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom2/']

But i want to know target key binding via its name? i.e. shutter -> <primary><shift><alt>a

I've figured out one simple but not convenient approach:

gsettings get org.gnome.settings-daemon.plugins.media-keys.custom-  
keybinding:/org/gnome/settin‌​gs-daemon/plugins/media-keys/custom-  
keybindings/custom0/ name
// return the name like `shutter`


gsettings get org.gnome.settings-daemon.plugins.media-keys.custom-  
keybinding:/org/gnome/settin‌​gs-daemon/plugins/media-keys/custom-  
keybindings/custom0/ binding
// return the binding like `<primary><shift><alt>a`

Does any guy know other elegant solutions?

Small script to find the keybinding by name

The script below will output the keybinding when you run it with the shortcut's name as argument. an example:

$ python3 '/home/jacob/Bureaublad/find_keybinding.py' rename
> '<Primary><Alt>r'

How to set up

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

  • Run it by the command:

    python3 '/path/to/find_keybinding.py' <shortcut_name>

Explanation

The information is in the output of

dconf dump /

On the custom keyboard shortcuts, this will output sections like:

[org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom9]
binding='<Primary><Alt>r'
command='/home/jacob/.local/share/nautilus/scripts/change_name'
name='rename'

As you can see, we need the line, two lines above 

name='rename'

...and so the script outputs that line, stripped from binding=

The script

#!/usr/bin/env python3
import subprocess; import sys
key = "/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/"
# read the output from dconf dump /, split into lines
ls = [l for l in subprocess.check_output(["dconf", "dump", key]).decode("utf-8").splitlines()]
# find line corresponding to searched name, print two lines higher
print(ls[ls.index([l for l in ls if "name='"+sys.argv[1] in l][0])-2].replace("binding=", ""))

Additionally

...you could create the directory ~/bin (if it doesn't exist yet) and save the script there without extension, and make it executable. Log out and back in, then simply:

find_keybinding <name>

will do

  • Thank you anyway. That inspires me to implement the same thing through shell. – e-cloud Jul 01 '16 at 08:31
  • @SaintScott I got a (very long) oneliner, but the python option is more robust. Not a single exception on the weirdest names, name clashes etc. – Jacob Vlijm Jul 01 '16 at 08:34
  • sorry, i mean, through shell script, actually doing the similar thing like yours – e-cloud Jul 01 '16 at 10:32
  • @SaintScott I understand, that's what I did as well, I actually have one, but doing it in python turns out to be more straightforward and robust. Also, the question mentions no language preference :) – Jacob Vlijm Jul 01 '16 at 10:34
  • i'm not rejecting your answer, but just comment. :) – e-cloud Jul 01 '16 at 10:44
  • @SaintScott Not taken as such! I was just commenting on your comment :) – Jacob Vlijm Jul 01 '16 at 10:45

    If @JacobVlijm's answer helped you, please take a moment to accept it. Thank you! – grooveplex Jul 04 '16 at 07:26
  • @SaintScott ^ just curious, but is there a specific reason why you wouldn't accept it? Both the Q & A were kind of on your request, in the comments of this answer: http://askubuntu.com/a/597414/72216 – Jacob Vlijm Jul 04 '16 at 07:34
  • sorry, i'm a newbie to ask a question that i didn't realized that i should accept the answer. :( – e-cloud Jul 05 '16 at 08:26
  • @SaintScott thanks! Only if it solves your issue in a satisfying way :) – Jacob Vlijm Jul 05 '16 at 08:34
  • I have tried executing this script with a number of inputs, but keep getting the same result:

    IndexError: list index out of range.

    I am assuming no such binding exists. If so, can somebody harden the script?

For custom keys try:

for i in $(gsettings get org.gnome.settings-daemon.plugins.media-keys custom-keybindings | awk -F"'" '{ for (i=2;i<=NF;i+=2) print $i }'); do
    echo "$(dconf read ${i}binding) $(dconf read ${i}name)"
done

For other keys, grep over the following command:

for schema in $(gsettings list-schemas | grep -E 'keybindings|media-keys')
do
    gsettings list-recursively $schema
done

Check this for more.
