I was wondering if anyone has figured out how to get custom keyboard shortcuts (e.g., setting Firefox to launch with alt + f) to work through Cinnamon Settings > Keyboard > Keyboard shortcuts > Custom shortcuts. I have tried a variety of different key combinations and applications to launch in the custom shortcuts, and I haven't managed to get any to work.
In earlier versions of Gnome 3 (before 3.5 or 3.6), I was able to set custom keyboard shortcuts using alt + (a letter), and it would work without any problems. Since about Gnome 3.5 or so, I noticed that custom shortcuts seem to have gotten messed up. At the time that Gnome updated to 3.5 or so, I was using Arch Linux, and I recalled that all of a sudden my custom keyboard shortcuts no longer worked. I installed Linux Mint 14 over my old Arch install, so I'm not entirely sure whether the custom shortcuts have been resolved in the latest versions of Gnome Shell in Arch.
I did some research and it seems that there might be an upstream problem with Gnome Shell custom keyboard shortcuts (gnome-settings-daemon problems) or with Ubuntu Unity and legacy gconf configurations.
Seehttp://askubuntu.com/questions/122748/e ... on-gnome-3https://bbs.archlinux.org/viewtopic.php?id=150587&p=1
(suggests that maybe this issue has been resolved in recent updates in Arch?)http://ubuntuforums.org/showthread.php?p=11834672
In addition, my research suggests that there might be a way to set the custom shortcuts manually with dconf of even gconf or gsettings
I installed dconf-editor and went into org.gnome.desktop.wm.keybindings. I noticed that all of those keybindings worked. Next, I went into org.gnome.settings-daemon.plugins.media-keys. There, I could manually change commands such terminal from the default ctrl + alt + t to something else like alt + t, and it initially worked.
Of potential importance, I noticed that under gnome.settings-daemon.plugins.media-keys there is a "Custom keybindings" listed. However, it appears that custom keybindings is empty per its description and  without any additional commands or text.
Based on what I had read from earlier research, I wondered if I could set the custom shortcuts in gconf. To that end, I installed gconf-editor. I navigated from Desktop > gnome > keybindings >custom, and I found that the firefox custom shortcut that I attempted to set through the Cinnamon settings was listed as:
However, even though this custom shortcut was listed, it would not work. After installing gconf-editor and restarting, all of my keyboard shortcuts from org.gnome.settings-daemon.plugins.media-keys (in dconf) were no longer working. In that manner, I could not open a terminal with alt + t or ctrl + alt + t. This setback makes me wonder if installing gconf and poking around gconf-editor somehow borked dconf and gnome-settings-daemon.
Also, another thing that I'm wondering is whether the non-custom keyboard shortcuts in Keyboard under Cinnamon Settings are controlled/being written into dconf, whereas the custom keyboard settings are getting controlled/getting written into gconf?
So, has anyone figured out a workaround to get custom keyboard shortcuts working?
Thanks for any potential help or suggestions.
