Some Further GUI Topics
This section discusses a number of different topics.
Mouse Buttons and Hotkeys
The GUI uses three mouse buttons. If you have fewer buttons on your mouse, the actions associated with the middle and right mouse buttons are obtained by shift-click, alt-click or control-click, depending on the computer.
The Main ident Window
In the main ident window the mouse buttons are used to drag and drop, to select/deselect models and data sets, and to double-click to get text information about the object. You can use the left mouse button for all of this. A certain speed-up is obtained if you use the left button for dragging and dropping, the middle one for selecting models and data sets, and the right one for double-clicking (actually for the right button, (Ctrl-click) a single click is sufficient). On a slow machine a double-click from the left button might not be recognized.
The ident window also has a number of hotkeys. By pressing a keyboard letter when it is the current window, some functions can be quickly activated. These are:
s: Computes Spectral Analysis Model using the current options settings. (These can be changed in the dialog window that opens when you choose Spectral Model in the Estimate pop-up menu.)
c: Computes Correlation Analysis Model using the current options settings.
q: Computes the models associated with the Quickstart.
d: Opens a dialog window for importing Data
Plot Windows
In the various plot windows the action of the mouse buttons depends on whether the zoom is activated or not:
Zoom Active: Then the left and middle mouse buttons are associated with the zoom functions as in the standard MATLAB zoom. Left button zooms in and the middle one zooms out. In addition, you can draw rectangles with the left button, to define the area to be zoomed. Double-clicking restores the original plot. The right mouse button is associated with special GUI actions that depend on the window. In the View plots, the right mouse button is used to identify the curves. Point and click on a curve, and a box will display the name of the model/data set that the curve is associated with, and also the current coordinate values for the curve. In the Model Selection plots the right mouse button is used to inspect and select the various models. In the Prefilter and Data Range plots, rectangles are drawn with this mouse button down, to define the selected range.
Zoom not active: The special GUI functions just mentioned are obtained by any mouse button.
The zoom is activated and deactivated under the menu item Style. The default setting differs between the plots. Don't activate the zoom from the command line! That will destroy the special GUI functions. (If you happen to do so anyway, "quit" the window and open it again.)
