MathML Ancestry

The MathML Ancestry is the status area displayed just below the Tabbed Toolbar, adjacent to the Mini Toolbar. The Ancestry is there to show you at a glance the nesting of the MathML structure at the cursor location, and to give you an easy way to select parts of the equation containing the cursor.

MathML ancestry

Since all MathML equations consist of templates nested inside a ‹math› element, the ancestry always shows the ‹math› element on the left. Intermediate MathML templates are listed in order of nesting, with the innermost MathML template at the cursor location indicated on the far right.

When there are too many levels of nesting to display all at once, the Ancestry shows dots on the right and/or left edge of the display. Clicking on the dots scrolls the display in the corresponding direction.

As you move the mouse, the Ancestry automatically updates to reflect the nesting at the current cursor position. Also, when you select part of an equation in the editing area, the corresponding template label in the Ancestry will be highlighted.

When you mouse over one of the MathML templates labels in the Ancestry, it will become highlighted in red. Clicking on a label in the Ancestry selects the corresponding part of the equation in the editor window. (In the screenshot below, the Tabbed Toolbar has been deselected in the View menu.)

A label in the ancestry becomes red when you mouseover it, and if you click it, MathFlow selects the corresponding part of the equation.

By double-clicking an Ancestry label, you can highlight the corresponding area of the current equation and simultaneously open the default Properties panel for that selection. Each kind of MathML template has a default Properties panel, depending on what MathML properties it supports. Changes to a Properties panel only affect the current selection. Sometimes a selection applies to several Properties. When this occurs, only the default panel is opened by double-clicking.
