On my Linux, the Alt-key is hijacked by the desktop so hitting the Alt-key alone isn't seen by Gimp. I can often circumvent this by using Alt-Shif or Alt-Ctrl. The combo is not intercepted and Gimp only cares about the Alt. Are there other place in Gimp where you can't use Ctrl, for instance to put a selection tool in subtract mode, or using Ctrl-click with a paint tool to sample a color?
