Hi folks ... Long time PC pro, but brand new to Apple, setting up my office desk space. Have a question I've not been able to answer anyplace else. Appreciate your thoughts on this. I keep my 13" MBA open at my right hand. I have a wireless keyboard in front of me with a 22" monitor in front of that. So I use both screens (swipe windows from screen to screen). And I use the laptop's trackpad for mouse navigation. Question is ... Can I customize a key or keys-combination, on the wireless keyboard, that will simulate 'holding the left mouse button' ? I would like to be able to hold a key on the wireless keyboard (with my left hand) while moving the mouse using the trackpad (with my right hand) thereby dragging and dropping. This would be more comfortable than the current setup which requires me to put both hands on the trackpad ... which is on my right side. Of course I can do this with two-fingers of my right hand on the trackpad, but only when moving short distances. So would appreciate feedback about customizing a key to simulate the left-click and hold event. Thanks Much, Fredster.
