The cursor is visible as a line in the palette view. It can be moved by clicking on an area beside a color.
The cursor has the following functions:
It points to the color after it. The color, if any, is described below the palette view. You may edit its name there.
It can be used to make a selection. A selection can be made by clicking on an area beside a color, so to move the cursor there, and by moving the mouse then with the left mouse button pressed.
If the At cursor check-box near the Add Color button is checked, a color from the color chooser is put at the cursor. The color is either inserted or it overwrites another one, depending on whether the Overwrite mode is chosen. The mode can be chosen by checking the Overwrite check-box, that is next to the At cursor one.
