Disable fill-handle-drag-and-drop via VBA

Greetings,
This is somewhat in reference to my previous thread.

The issue with this kind of thing is that Excel has built in functions which occur when you double click, alt + click etc. etc.
Now, with the Alt + Click, the research pane comes up. I've counteracted this by temporary disabling the research pane during the course of the macro:

My issue with double click is that if someone double clicks the border of the cell, it will select the end of the column/row/etc (similar to how Control + Up/Down/Right/Left) does.
There IS a method of disabling this - it involves going into the options menu and disabling the drag-and-drop fill handle:

However, that's quite a useful function and I'm not massively comfortable disabling it - plus, the settings wouldn't carry over to others using the spreadsheet (I think?)
Is there a VBA method of doing so - so that I could disable it on the start of the macro and reenable it at the end?
Thanks,

EDIT:
Guys I'm very sorry for wasting your time. A quick "record actions" on excel figured it out for me. For future reference if anybody comes across a similar issue:
