    Description

      I have assigned several key functions (Delete, BackSpace, Left, Right, Home, End, Up, Down, PageUp, PageDown) to letter keys on 3-rd and 4-th level in /usr/share/X11/xkb/symbols/us and /usr/.../ua.
      This is an example of rebound Delete and BackSpace in /usr/share/X11/xkb/symbols/us ("dvp" variant):

      key <AC03> { [ e, E, BackSpace, BackSpace ] };
key <AC04> { [ u, U, Delete, Delete ] };

      Qt4: none of these rebound keys is accepted by QTextBrowser, QTextEdit; only BackSpace is accepted by QLineEdit. I have inactive QTreeWidget in the same QMainWindow and it handles keys, which are not accepted by active text widgets.

      Qt5: all these keys are accepted by QLineEdit; only BackSpace is not accepted by QTextBrowser, QTextEdit. As in Qt4, BackSpace is handled by inactive QTreeWidget in case of active QTextBrowser or QTextEdit.

      There was a similar (only directional keys) issue: QTBUG-26302 . Looks like it was fixed only in Qt5...
