The editor search procedures search for a particular item and move the editing
cursor and xview position if a search item is found. Each search command takes
a direction and a search string. Direction can be either '
30717' then the editing cursor is moved to that consensus base. If value is '
@' followed by a number (eg '
@100') then the editing cursor is moved to that base within the current reading. If value starts with a plus or minus the editing cursor is moved forwards or backwards by that amount. The direction parameter here has no effect and is included purely for consistency.
verifyandlooks for evidence on both strands together.
verifyorlooks for evidence on each strand independently and defines a match to be places where either strand has a lack of evidence. In the current implementation of these two searches only the forward direction is supported.
