Source editing

This menu contains the actions for exporting to and importing data from the system clipboard, as well as undoing actions, selecting content, and performing a find & replace.

The Source view editor acts as a standard text editor, therefore selection, cut/copy, and paste operations only utilize text data and add no special formatting.

The clipboard can be used in two ways. First, the clipboard is useful for cutting and pasting within the Editor. Second, the clipboard is useful for pasting data into other applications. Equation data targeted for other applications in general requires additional formatting. For example, some XML applications may require a namespace prefix for MathML markup.

There are several commands in the Edit menu. Details follow, including shortcut keys:

Undo ( Ctrl+Z )

This command reverses the last cut, paste, or text editing operation. You can undo the last 100 operations.

Redo ( Ctrl+Y )

This command reapplies the last cut, paste, or text editing operation that was undone. You can redo operations up to the point of the first undo.

Cut ( Ctrl+X )

This deletes the selected MathML or text from the editor, and places it in the system clipboard (so it can be pasted into other applications).

Copy ( Ctrl+C )

This copies the selected MathML or text from the editor, and places it in the system clipboard (so it can be pasted into other applications) without removing the selection from the current equation.

Paste ( Ctrl+V )

This command pastes the contents of the system clipboard into the editor window at the current cursor location. Only text content will be accepted.

If the MathML on the clipboard was placed there by the MathFlow Editor, it can always be pasted back into the Editor regardless of how it is formatted. Although Source view will allow any text to be placed into the editor, the data/equation must be in valid MathML format, and it MUST be enclosed by ‹math› tags. It will not paste clipboard data as MathML unless it begins and ends with ‹math› tags. It is recommended to use the Validate command after a paste to check for any MathML errors (see the next section, Source menu, for details). Also, the editor will ignore any data on the clipboard before the opening math tag, and after the ending math tag.

Select All ( Ctrl+A )

This selects the entire MathML source currently in the editor.

Find/Replace ( Ctrl+F )

This option operates just like most any text editor Find & Replace feature. The command will find instances of the specified text in the selection or entire document and if needed, replace any or all instances with specified text.

This menu contains the actions for formatting and validating the MathML source; it is only available in Source view.

There are two commands in the Source menu:

Source view is designed with some clear visual cues to assist in viewing and editing the structure. To this end, the Editor uses four colors to differentiate the major components:
