This dialog, invoked from the Edit/Search... menu item, allows you to specify a value of any type to search the file for.
The radio buttons in the 'Start From' box allow you to choose whether to begin the search from the top of the file or the current caret position. Note that even if you choose to start from the top of the file, you can still use the Find Previous and Find Next buttons on the toolbar to do the same search again from the current caret position.
The 'Search For' field allows the value to be searched for the be entered. The string typed here will be interpreted differently depending on the 'Type' chosen.
The 'Type' listbox contains a list of types. The string entered will be interpreted as representing the type chosen here, and the result of the search will change accordingly. Some types have additional options; strings may be case sensitive or case insensitive, and integers may be in Intel or Motorola format. The checkboxes representing these options are enabled only when an appropriate type is selected.
The radio buttons in 'Action' determine the action taken when a match is found. If 'Goto' is chosen, then the search ends when the first match is encountered, and the view and the caret are both moved to that offset. If 'Mark' is chosen, then the whole document is searched, and regions of bytes that match the search term are marked. Even if 'Mark' is chosen, you can still skip from one occurrence of the search pattern to the next using the Find Previous and Find Next toolbar buttons.
When 'OK' is clicked, AXE performs the search, either marking bytes or moving the view. If no matches are found, a message box is displayed so as to reassure the user that the search was in fact made.
