Once she becomes familiar with the layout of the menu, she can simply move the mouse immediately without holding the button, without viewing the menu.

Copy them Paste them Move them to their final position Gestures often mimic proofreader's marks, which are widely-accepted and intuitive, but where proofreader' marks merely describe intended changes, gestures actually edit texts and graphics. But whatever the display, artists can focus on their art, rather than wasting time and attention on their tools. In addition, Sketch streamlines the most common editing operations. Single shapes are selected by merely pointing, as in web browsers, not by clicking, as in conventional drawing programs.
