Hello Jimmy,
You just need to customize your toolbar to achieve this. Have a go with the
following:
1) Ensure the Drawing window is the active window and right-click on one
of the existing toolbar buttons and select 'Customize...'
2) In the dialog, click the Commands tab and select 'View' from the
left hand listbox.
3) Select the 'Zoom Out' item in the right hand listbox and drag and drop
it where ever you want it appear in the toolbar.
4) Repeat item 3 for 'Zoom In'
5) Close the dialog and you're done.
Best regards
John
