The horizontal tool bar
Below the menu bar is the horizontal tool bar. The icons in this tool bar enable you to access a number of the most frequently used standard functions.

The individual icons are either assigned to the left column (tree structure) or the center column (editing area).

If either of the columns is not wide enough to display all of the icons, the icon is shown on the right-hand edge of the column. Clicking on the icon will open a selection list of all other functions.
