Tip - Three Fingers to Drag Items on the Mac
I don't know why Apple hides this feature.
Go to the Accessibility preference pane and choose Mouse & Trackpad from the left pane. Click on Trackpad Options
From the drop-down menu select Enable dragging and choose three finger drag from the drop-down selector next to it.
Now in the Finder, you can select a file and use three fingers on the keyboard to drag it to a new location. In your text editor, you can select a section with three fingers and drag it to another location in your file. The three finger drag will work in moving objects around in a whole slew of applications.
I still don't know why Apple hides this feature. Shouldn't it be in the Trackpad preference pane?
