EditPad offers 13 search options. By default all these have abbreviated buttons on the Search toolbar. You can toggle them with Alt+letter key combinations when the search toolbar or search panel has keyboard focus. You can also toggle them via the Search|Search Options menu item. Directly clicking this menu item shows a popup dialog with a checkbox for each option. If you only need to toggle one search option, it is quicker to use the submenu of Search|Search Options to toggle that option.
These options only affect searches done via the search toolbar or search panel. For instant searches, there is a separate reduced set of Instant Search Options.
