Detailed Description

Allows Emacs-style key sequences (for example "Ctrl+E, Ctrl+2") no longer than four combinations. See the documentation of QKeySequence for details.

When ShortcutLineEdit receives the focus, its whole contents get selected. On a key press, if any of the contents are selected, the new key replaces all the previous contents. Otherwise, it's appended to the sequence.
