Toolbar Quick Search
One way to do simple searches is to enter text in the search area of the toolbar. This scrolls as you type to the next match found after the current cursor position. Pressing Enter will search for each subsequent match, wrapping the search when the end of the file is reached.
Text matching during toolbar quick search is case-insensitive unless you enter a capital letter as part of your search string.
If focus is off the toolbar search area and it already contains a search string, clicking on it will immediately start searching in the current source editor for the next match. If you wish to search for another string instead, delete the text and type the desired search string. As you delete, the match position in the editor will proceed backward until it reaches your original search start position, so that after typing your new search string you will be presented with the first match after the original source editor cursor position.
