Using KDE 4.14.13, Fedora 22, kdm desktop manager, if I type Tab to try to do command line completion I get the KDE accessibility tool dialog asking me if I want to enable Sticky Keys and Mouse Keys.  No matter what I answer I can't get this to turn off.  Tab works as expected when using konsole or gnome-terminal.
Tab in xterm under KDE always brings up accessibility tool dialog
