I would like to add the windows calculator as an option in any toolbar
1. Right-Click your toolbar and click Customize.
2. The customize toolbar dialog appears. Click the Commands tab.
3. Drag *any command* to your toolbar and position it where you want it.
4. With the dialog still open, right-click your new button and click
Properties
5. You get a properties dialog that lets you customize everything about the
button
6. Specifically, in the On Action, put this: = Shell("Calc.exe")
