Comment 14 for bug 167290

If anyone tries builds from 20924 onward, they can try the options/trackalt/value = 1. The default is 0 which is the current behavior of trusting Gdk's interpretation of keyboard state. A non-zero setting will attempt to track the Alt key manually by watching for GDK_KEY_PRESS events of GDK_Alt_L and GDK_Alt_R types. This works for me, and I tried to make this as benign and safe as possible, but I want to know if it works for other people, or if it causes problems for other people.
