Is there a way to bold and color an individual character in an edit box?  (Using D5, in other words, if an edit box says "this is a test", I want to make "a" bold and green, an change it on the fly)

That formatting would require a different control, such as RTF or web browser.

You could display the text formatted by printing on a canvas.  This would not be an editable control.

You can use TRichEdit setting
  RichEdit1.WordWrap := False;
  RichEdit1.WantReturns := False;
set also its height to such as edit

Along with mokule's answer, here is how to do it:

procedure TForm1.RichEdit1KeyUp
  ( Sender: TObject;
    var Key: Word;
    Shift: TShiftState
  loc: Integer;
  oldcolor: TColor;
  oldStyle:  TFontStyles;
  oldcolor := RichEdit1.SelAttributes.Color;
  oldstyle := RichEdit1.SelAttributes.Style;
  if Key = 65 then
    loc := RichEdit1.SelStart;
    RichEdit1.SelStart := loc-1;
    RichEdit1.SelLength := 1;
    RichEdit1.SelAttributes.Color := clGreen;
    RichEdit1.SelAttributes.Style := [fsBold];
    RichEdit1.SelStart := loc + 1;
  RichEdit1.SelAttributes.Color := oldcolor;
  RichEdit1.SelAttributes.Style := oldstyle;

I think this could be done by using some winapi functions, but this is not the easiest way.

Correct as was stated by aikimark. The standard Windows
Edit control does not support colors, UNLESS, you do all
the drawing yourself and that would take a lot more
code than is shown.
