Map mouse click in Apple Calendar, to a Function Key


Complete newbie user for BTT here. Have searched the forum but couldn't find the answer. I use Apple's default OSX Calendar app, and need to frequently toggle on/off up to 6 calendars. As far as I can tell, this toggling procedure can only be done via a mouse click (of the relevant calendar's check box) in the app's 'Calendar List' sidebar. I'd like to map each mouse click (ie toggle a given calendar on/off) to a function key.

Can BTT do this?
