Vivian pointed out that a redefined Ctrl-U key binding didn't work correctly. I found out that this is, because the definition in $FG_ROOT/keyboard.xml sets <value type="bool"> for binding[1], and ... [better sit down first!] ... and assigning <value type="double"> in a *-set.xml file doesn't *really* set "double" as new type! Instead, the boolean is kept, and a double sqeezed into it. In other words: once tainted as bool, you can throw all doubles in the universe on a property node, and all it will accept is 0 and 1. Without warning! BTW: I changed the patch: I was overly cautious: clear_value() does already care for ties and for setting NONE, so we just need to make that public as clearValue(), and use that. Makes the patch a bit more verbose, though. :-/
