One never stops learning. I was reminded of this just very recently when I discovered a very cool feature of GTK+ which I wasn’t aware off even though I have been using Linux-based OS as my main OS for more than 10 years now.

With editable menu accelerators it is possible to astonishingly easily change menu short cuts for actions directly in menus. For this to work gtk-can-change-accels=1 has to be added to the ~/.gtkrc-2.0 file. When this is in place menu short cuts in GTK+ applications can be changed simply by hovering with the cursor over a respective entry and pressing a new short cut. With backspace short cuts can be deleted. I found this information from the Xfce FAQ.
