Settings can be turned on and off by choosing the check box with the <Spacebar>, with <Enter> key or by
left clicking with the mouse on it. If a check box has an symbol in it, the setting is on. More than one box in
a group can be checked at a time.
Radio Button
Unlike check boxes, only one radio button can be chosen at the same time. Select the radio button and press
the <Spacebar>, the <Enter> key, or click with the mouse on it. When a radio button is chosen, a bullet
appears and any previously chosen radio button in the group becomes deselected.
Text / Data Box
A text/data box is a field that displays pieces of information from the database (e.g., meteorite name, country,
terrestrial age...). These kinds of fields are set read-only and cannot be edited.
In some dialogs, so called edit text boxes are used, where you are asked by the program to enter text. This can
be a number or a string of characters (e.g., the name of a meteorite that MetBase shall locate in the database).
To enter text in the box, press the <Tab> key until the edit text box is selected (yellow highlighted) or click on
the edit text box with the mouse to position the cursor. Type in the text and press <Enter> to execute the
program according to your specification. To exit an edit text box, press the <Tab> key.
Popup Control
Tab or Shift+Tab to the popup control or click with the left mouse button on the popup. The selected item is
highlighted in blue color. To display the contained popup items, hold the left mouse button pressed and drag
up or downwards in the popup listing. You can also click on the right scroll bar to display further items not
fitting on the popup field. Release the left mouse button to select the highlighted item. You can instead use the
<Up> or <Down> Arrow keys in conjunction with the <Alt> key to open the popup list. To select an item,
press <Enter>. You can further use <PgDn> and <PgUp> to scroll the list one full window at a time.
<Home> and <End> move you to the first or last option in the popup listing.
List Objects
List objects in dialog windows usually contain text information of variable length. If there is more text than
the list box can display, the arrows of the right scroll bar are enabled (black). For scrolling with the keyboard,
Tab (forward) or Shift+Tab (backward) to the list, then use the <Up> or <Down> Arrow keys to scroll
through it. For scrolling with the mouse, click on the up or down arrow on the scroll bar. If you hold the mouse
button down, scrolling will continue until you release the mouse button. To scroll rapidly, point to the thumb
and drag it up or down.
