You can add a tool in the following way:
Select Customise from the Tools menu from within any mode. The Tools dialog box is displayed.
Press the New… button. The Tool property sheet is displayed, showing the Details page.
Enter a name for the tool, for example, 'Calculator'. Specify the full path of the relevant program or file, for example, 'C:\WINDOWS\CALC.EXE'. You may use the Browse… button to locate the required file. If you are specifying a program which requires arguments then enter those arguments in the Arguments field.
In the Visibility page, choose whether or not you wish to show the tool in the menu by checking the View in menu check box. If you wish to show the tool in the menu in each mode, then select 'All Modes' from the Mode drop down list. If you wish to show the tool only in a specific mode, then select that mode from the Mode drop down list.
If you wish to view the tool in the main toolbar then check the View in toolbar check box.
The Access page lets you choose whether this tool is a public tool, available to all users or whether it is a private tool, accessible only by you. Select either the Public or Personal radio button accordingly.
