Enable search highlight: Select to highlight the search term match found in the
code when you perform a search. Clear to prevent the highlighting. In both cases,
the pointer appears after the last character of the search term match.
l
Double click line: Select to highlight the complete line of code when you double-
click that line. Clear to highlight only the word under the pointer.
l
Find text at cursor: Use to set the behavior of the Find dialog box. Select to
automatically copy the word under the pointer into the Text to find box when you
open the Find dialog box. Clear to prevent the copy. If no previous search terms
appear in the Text to find drop-down list, the Editor performs the copy regardless of
whether this option is selected or cleared.
l
Block indent: Enter the number of spaces to jump for each block indent. The
default is 2 and the maximum is 16. The Block indent typically should agree with the
tab stops in the Tab stops option. Perform a block indent by selecting a region of
code and pressing CTRL+SHIFT+I (to indent the code to the right) or
CTRL+SHIFT+U (to move the code to the left).
l
Tab stops: Use to set the number of spaces to advance when you enter a tab
character or to set a series of tab stops. Enter a single integer to set the number of
spaces to advance with each tab. Enter a sequence of two or more integers, each
separated by a space, to specify tab stops. The sequence must be in ascending
order. Tab stops are measured in number of space characters. For example, a value
of 20 places the tab stop at the 20th space character. You can also use the drop-
down list to select a previously entered value.
