You can modify existing toolbars as described below. First, access the Customize dialog box by selecting the View | Toolbars | Customize menu option, and click the Toolbars tab.
To add a menu item to a toolbar:

PC-DMIS also allows another way to rearrange or delete items from any custom toolbar on the fly. This is by using the Shift key. Consider the following:
To delete or rearrange a toolbar's icons:
Press and hold the Shift key.
Click and drag an icon. The icon becomes movable.
If rearranging the icon, drag it to a new spot on the toolbar.
If deleting the icon, drag it outside of the toolbar's boundaries.
Release the mouse button. The change is made.
Since existing toolbars must have at least one icon on them, if you remove the last icon in this fashion, it only remains removed until you restart PC-DMIS. After restarting, the icon reappears.
To add a separator:
Press and hold the Shift key.
Click and drag an icon to move it.
Drag it a small distance to the right (not far enough to rearrange its position).
Release the mouse button. The software places a separator to the left of the icon.
To delete a separator:
Press and hold the Shift key.
Click and drag the icon to the right of the separator. The icon becomes movable.
Drag it on top of the separator to its left.
Release the mouse button.
