Add formula to cell with a mouse click

I would like to figure out how to write a formula to put an X in a cell with a right mouse click. Can this be done or am I dreaming?

Superdave66,

Thanks for changing your title, however its still not as per the forum rules. Please change it to something like "formula to put an X in a cell with a right mouse click". Appreciate your co-operation.

Hello Dave,

I've changed your title to something a bit more relevant.

In VBA you would go to the sheet in question and add the following Before right click event.

You could also use the same code in the double click event if you prefer. Just change the A1 reference to whatever cell you have in mind.
