When you want to resize a window in gnome (as well as in other systems) you can click-and-hold at the window's border and than drag it. The problem is (and do correct me if I'm wrong here) that the draggable border is just a couple of pixels thick in gnome. That tends to be a little frustrating, and contributes to my wrist pains from using the mouse, as it requires very careful movement of the mouse.
How can I change the thickness of the area I can click in order to resize a window? I don't want to increase the appearance of the window border, I'm not talking about eye candy here. I want to fine tune this functionality where I can resize a window by dragging its border.
Is there a setting somewhere that will change this?
alt + middle-click
doesn't involve changing appearance. It's not strictly changing the border width, but it solves the same problem. In fact, it gives you a much wider area (the whole window) than you would get by changing the border width.
