Named indexes

Much like the INSERT name we saw previously, Tkinter has many others we can use as shortcuts to finding locations within our Text widget. These include:

  • CURRENT: The character closest to the mouse cursor. This updates when the mouse is moved and no buttons are pressed.
  • END: The final character of the document. This is very useful for clearing the entire widget, as we know the start is always 1.0.
  • SEL_FIRST: The first character which is selected.
  • SEL_LAST: The last character which is selected.

These named indexes are not the only conveniences offered; there are also special strings that can be used to calculate indexes, but that do not reside in the built-in constants.
