Change 'Clear History' shortcut

[Former user]

Ctrl + N shortcut used to clear history is quite common shortcut in other programs (eg. open new tab/window). I have unintentionally cleared history a few times as I didn't notice SpeedCrunch window had the focus and lost some results of calculations I haven't saved yet.

Possible solutions - ability to change or remove the shortcut, or - show confirmation dialog before clearing the history

Added dialog would require user to press a sequence of Ctrl + N → Enter to clear history. Or Esc instead of Enter to cancel.
