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.

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.
