You could use the keyboard shortcut (Ctrl-F).
You could add an icon to your favorite toolbar.
Tools|Customize|Commands Tab|Edit Category (near the bottom--look for
binoculars).
Or you could have a macro that looks like:
Option Explicit
Sub ShowFindDialog()
Application.Dialogs(xlDialogFormulaFind).Show
End Sub
To make it available quickly, you could assign it to a shortcut key. Maybe
ctrl-F, hey, wait! (or put a button from the Forms toolbar on your worksheet
and assign this macro to the button.)
Since you're new to macros, you can read some notes at David McRitchie's site:
