The Default ToolBar in GeoGebra WebStart 2.7
In GeoGebra WebStart 2.7, including the line
<param name=showToolBar value="true">
in the applet call displays the default toolbar with its nine buttons
<p/>
Clicking any one of these buttons will set the current mode.
Each button also shows a small down-arrow.
Clicking on a down-arrow (or anywhere on a button's lower edge) opens a drop-down list ("menu").
The selected button becomes the default in that position and sets the current mode.
Here are all the icons of the default button layout with their mode code.
(There is no icon for mode=43 which is Algebra Input.)
The name (in English) of each code can be found at
