Locate Strings can be edited in the edit field between the prev and next buttons in the function bar.
In addition to the classic Search Dialog (Ctrl-QF) and the Incremental Search (Ctrl-QG), "Locate Strings" are the third possibility to search text strings in a text. In opposite to the other two variants which only move the cursor, all occurences of the string get highlighted in the text simultaneously. With the Prev and Next key, you can jump to the next highlighted expression in the text. The Locate String Window is not case-sensitive.
In the locate string edit field, you can concat several strings simultaneously, separated by semicolons:
Bush;Bin Laden;Saddam
The expressions in the text gets highlighted with different colors; the fourth expression
gets the color of the first expression again and so on. It is allowed to use spaces
in the expression, but if the expression in the text is part of two different
lines, the text won't be found.
