The Reflect tool (O) flips objects over a fixed axis. 
The Rotate tool (R) rotates objects around a fixed point. 
The Scale tool (S) resizes objects around a fixed point. 
The Shear tool skews objects around a fixed point. 
The Reshape tool adjusts selected anchor points while keeping the overall detail of the path intact.
The Free Transform tool (E) scales, rotates, or skews a selection.
The Blend tool (W) creates a series of objects blended between the color and shape of multiple objects. 
The Width tool (Shift+W) allows you to create a stroke with variable width. 
The Warp tool (Shift+R) molds objects with the movement of the cursor. 
The Twirl tool creates swirling distortions within an object. 
The Pucker tool deflates an object by moving control points towards the cursor. 
The Bloat tool inflates an object by moving control points away from the cursor.

The Crystallize tool adds random spiked details to the outline of an object.
The Wrinkle tool adds wrinkle-like details to the outline of an object. 
The Shape Builder tool merges simple shapes to create custom, complex shapes. 

The Symbol Sprayer tool (Shift+S) places multiple symbol instances as a set on the artboard.
The Symbol Shifter tool moves symbol instances and change stacking order.

The Symbol Screener tool applies opacity to symbol instances. 
The Symbol Styler tool applies the selected style to symbol instances. 

The Column Graph tool (J) creates graphs that compare values using vertical columns.
The Stacked Column Graph tool creates graphs that are similar to column graphs, but stacks the columns on top of one another, instead of side by side. This graph type is useful for showing the relationship of parts to the total.
The Bar Graph tool creates graphs that are similar to column graphs, but positions the bars horizontally instead of vertically.
The Stacked Bar Graph tool creates graphs that are similar to stacked column graphs, but stacks the bars horizontally instead of vertically.
The Line Graph tool creates graphs that use points to represent one or more sets of values, with a different line joining the points in each set. This type of graph is often used to show the trend of one or more subjects over a period of time.
The Area Graph tool creates graphs that are similar to line graphs, but emphasizes totals as well as changes in values.
The Scatter Graph tool creates graphs that plot data points as paired sets of coordinates along the x and y axes. Scatter graphs are useful for identifying patterns or trends in data. They also can indicate whether variables affect one another.
The Pie Graph tool creates circular graphs whose wedges represent the relative percentages of the values compared.
The Radar Graph tool creates graphs that compare sets of values at given points in time or in particular categories, and is displayed in a circular format. This type of graph is also called a web graph.

The Hand tool (H) moves the Illustrator artboard within the illustration window.
The Print Tiling tool adjusts the page grid to control where artwork appears on the printed page.
