Separate a tool from its flyout

Step 1 - Display the Customize dialog
Choose View > Customize (or right-click in an empty area of the workspace and choose Customize from the context menu) to display the Customize dialog.
Step 2 - Drag tool to new location
In the Tools toolbar, drag the desired tool to its new location. For example, to separate the Zoom tool from the Pan tool, drag the Zoom tool from the Pan/Zoom flyout to a new Toolbar location.
*Optional: Step 3 - Reset the Toolbar
*Optional* To reset the Tools toolbar to its default arrangement: a) display the Customize dialog; b) choose the Toolbar tab; c) select the Tools option so it's highlighted; d) and then click Reset. When asked to confirm this action, click Yes.
Notes and Tips:
To rearrange the order of the tools, display the Customize dialog and then drag the tool/tool group (not from the flyout) to its new location.
Be aware that you can place often-used tools directly into any toolbar. This can be especially useful when creating a custom toolbar.
