Increases the indent by the size of one tab or inserts the tab.
If the line in a document is selected, the TabKeyCommand command increases the indent of paragraph(s) which contains selected line(s) by the size of one tab. If the selected paragraph belongs to the numbered or bulleted list, the command increments the indentation level of a paragraph. If a part of a line is selected, the command inserts a tab.
In a table the command moves from cell to cell. When selection is in the last column of the last row in a table, the command adds a new row.
