int iIndx = this.rtbFileTxt.Find(strFind,
this.rtbFileTxt.SelectionStart,
RichTextBoxFinds.None);

if (iIndx < 0) return false;

this.SuspendLayout();
this.rtbFileTxt.SelectionStart = iIndx;
this.rtbFileTxt.SelectionColor = Color.Yellow;
this.rtbFileTxt.SelectionBackColor = Color.Black;

Point ptCharIndx =
this.rtbFileTxt.GetPositionFromCharIndex(this.rtbFileTxt.SelectionStart);
if (ptCharIndx.Y > this.rtbFileTxt.Height)
this.rtbFileTxt.ScrollToCaret();
this.ResumeLayout(true);

- Solution 2:

If you want to get character index when mouse moves, you can
get convert Cursor.Position to x and y values of a Point type
which are related to your control (RichTextBox) by calling
.PointToClient( ... ) method, and then call GetCharIndexFromPosition
method to find out the character position.

private void rtbCntrl_MouseMove(object sender, MouseEventArgs e)
{

Point rtbPos = this.rtbCntrl.PointToClient(Cursor.Position);
int iCharIndx = this.rtbCntrl.GetCharIndexFromPosition(rtbPos);
