ShowCursorTracker

ShowCursorTracker

is an option for Cell that specifies whether an elliptical spot should appear momentarily to guide the eye if the cursor position jumps.

Details

  • The default setting is ShowCursorTracker->True.
  • Line breaking is normally set up so that small changes to expressions in input cells rarely cause largescale reformatting; the cursor tracker appears whenever reformatting is required that makes the cursor position jump.
  • The cursor tracker is intended to be sufficiently eyecatching to make the lowlevel human visual system cause an immediate shift in gaze.

Examples

Basic Examples  (2)

Here is a sample expression cell:

In[1]:=
Click for copyable input

This turns cursor tracking on in the sample expression cell:

In[2]:=
Click for copyable input

Add and delete a character a few times in the sample expression cell:

In[3]:=
Click for copyable input

Here is another sample expression cell:

In[1]:=
Click for copyable input

This turns cursor tracking off in the sample expression cell:

In[2]:=
Click for copyable input

Now the cursor tracker does not appear when you edit the sample cell:

In[3]:=
Click for copyable input
