A text% object is a standard text editor. A text editor is displayed on the screen through a editor-canvas% object or some other display.
The line-spacing argument sets the additional amount of space (in DC units) inserted between each line in the editor when the editor is displayed. This spacing is included in the reported height of each line.
See set-tabs for information about tabstops.
A new keymap% object is created for the new editor. See also get-keymap and set-keymap.
A new style-list object is created for the new editor. See also get-style-list and set-style-list.
