Editing the Current Window
Editing a window is performed by clicking the Edit.. button at the top left of the program after first selecting the required window.
A dialog is then used to change any of the parameters for the window.
Note that the Main window can't be edited.
Properties Menu and Button
A simple Properties menu can be called from the Properties button in the toolbar. If the toolbar has been hidden, then a button appears at the top right of the program.
The Properties menu can be used to show and hide the toolbar and the status window, register the program and show an About box.
Splitting the Screen
Note the Split... button at the top of the program.
This can be used to show more than one of the windows at the same time, either split horizontally, vertically or as four quadrants.
The split command can also be called from the Properties menu.
When the screen is split, the Split... button becomes Single..., which can be used to return the program to the normal one window mode.
