To speed up my workflow, I'm trying to assign the most often used dialogs/actions to one-button keyboard shortcuts, but I'm stuck with "d" and "g" keys which can't be redefined by editing shortcuts.xml file. Whatever I set in this file, "d" is alway shortcut for "Pick color" tool, and "g" is for "Gradient" tool.

Could anybody point me where should I look for those shortcuts in Inkscape source code? It looks like I have to remove two lines of code to fix my problem, but Inkscape codebase is huge and I have no idea where to look, shortcuts.cpp seems to contain functions for processing shortcuts, but I can't find keybindings itself.

Good question. There shouldnt be any hard coded ones is the answer, but obviously we have a bug...

Update: I've just noticed that "g" can be redefined, but it is definitely impossible to change "d" keybinding using default.xml file, so I filled a bug https://bugs.launchpad.net/inkscape/+bug/269531
