To use the action keys
1 If the action key uses the contents of the entry buffer, place the desired information
in the entry buffer.
2 Position the mouse pointer over the action key and click the action key.
Action keys are user-definable pushbuttons that perform interface or system
functions. Action keys can use information from the entry buffer — this makes it
possible to create action keys that are more general and flexible.
Several action keys are predefined when you first start the Graphical User
Interface. You can use the predefined action keys, but you’ll really appreciate
action keys when you define and use your own.
Action keys are defined by setting an X resource. Refer to Chapter 10, "Setting X
Resources" for more information about creating action keys.
To use dialog boxes
1 Click on an item in the dialog box list to copy the item to the text entry area.
2 Edit the item in the text entry area (if desired).
3 Click on the "OK" pushbutton to make the selection and close the dialog box, click
on the "Apply" pushbutton to make the selection and leave the dialog box open, or
click on the "Cancel" pushbutton to cancel the selection and close the dialog box.
The graphical interface uses a number of dialog boxes for selection and recall:
Directory Selection Selects the working directory. You can change to a
previously accessed directory, a predefined directory, or
specify a new directory.
File Selection From the working directory, you can select an existing file
name or specify a new file name.
