I am trying to change the shortcuts used to move windows while switching workspaces, in Ubuntu 12.04.
The problem is that the shortcuts that I want to use include the combination of Ctrl and W, which closes the window "Settings>Keyboard>Shortcuts>Navigation". So I edited the file ~/.gconf/apps/metacity/global_keybindings/%gconf.xml to modify this entry:
<entry name="switch_to_workspace_right" mtime="1416437209" type="string">
<stringvalue><Control><Primary><Alt>w</stringvalue>
</entry>
I only replaced the right arrow by the letter 'w', so now my shortcut for switching to the workspace on the right is "Ctrl+Alt+w".
I now would like to move a window while switching workspace, using "Ctrl+Alt+LeftShift+w" (same as before, with an additional Shift). But then again, I cannot do it through the Navigation window, and this time I do not have any existing code in %gconf.xml that I can modify. I could not find anything about the meaning of mtime, or the global syntax of such an entry.
So my question is: what code should I write in %gconf.xml, or where can I find that piece of information? I am just asking for search assistance, not necessarily for someone to completely solve my problem.
Thank you for any help that you may provide.
