A typical use of this feature is to tell the editor to find the source of an error
by plumbing the file and line information in a compiler's diagnostic.

+On Mac systems, the Option key changes the main button to button 2,
+and the Command key changes it to button 3.
+Pressing the key after the button is held down adds the button to form
+a chord, so that for example on Macs selecting text with the trackpad
+button and then typing Option without letting go of the button will
+cause a 1-2 chord, cutting the selection.
+On Mac systems, the usual keyboard shortcuts
+Command-C, -V, -X, and -Z invoke
+copy, paste, cut, and undo,
+and Command-Shift-Z invokes redo,
+as in other programs.
+Especially on Mac laptops, these keyboard shortcuts are
+typically much less awkward than the equivalent chords.
