Version: 2.9.6 (using KDE 4.5.2) OS: Linux Yakuake uses C-_ (or Ctrl+Shift+-) key combination for shrinking the font, but this combination is used by both GNU Bash and GNU Emacs for undoing the last typings and it's not good to bind it to something else. This binding may be turned off in Konsole's keyboard setup dialog, but, for some reason, not in Yakuake's one! This bug is especially terrible if you are using the Terminus bitmap font in your terminal and after preesing C-_, instead of undoing last actions, the whole text turns into squares leaving you to guess what's just happened. That's why I marked it as "data loss" below. Reproducible: Always Steps to Reproduce: Open terminal by F-12 and press Ctrl+Shift+-. Actual Results: Font shrinks. Expected Results: Mistypings undone. As an alternative, the keyboard bindings dialog should let me turn off this binding, just like in the Konsole.
