Can I change the hotkey for these commands?

[kyjdp]

In the use of QM software process, often used breakpoint command、output clear command， the default command of the hotkeys is M-click, look at the following picture, but now many mouse are the mouse wheel as Middle Key, the use is not convenient, if I can put the hotkey into the mouse double-click, much more convenient, I did not find the option to set the option hotkey, so consult! Explained as follows:

1:
Click the row number: can select the current row (default)
Right-click the line number: can comment on the current line (default)
Double-click the line number: can breakpoint the current line

2:
double-click in the blank space of the output window: clear output
