It seems Keyboard Shortcuts launch user command from the root directory, rather then current user home. Take an example:

As "gedit" is launched from the root directory, the default save location is also the root instead of default user home.
I know I can make it always be launched from the user home by:
sh -c 'cd $HOME; gedit'
But I'm bored to wrap them in a shell each time I add a keyboard shortcut. I'd like to know whether I can configure Keyboard Shortcuts so it will be in the current user home by default.
(I don't know which package Keyboard Shortcuts belongs to, so please add the correct tags for me)
