Cursor beyond EOL: Select to make it possible to position the pointer beyond the
end of the line. Clear to prevent this.

Keep trailing blanks: Select to preserve any blank spaces occurring at the end of a
line. Clear to remove those blank spaces.

block of code appended to that block of code as part of the selection. When you
select this option, you can also use the arrow keys to move within the code without
affecting the selected code. You must select the Enable selection option to use the
Persistent blocks option.

Overwrite blocks: Select to have any text you enter immediately after selecting a
block of code replace that block of code. You must clear Persistent blocks and
select Enable selection for this option to have an effect.

Enable selection: Select to permit the creation of selections in the Code area. If
selected, you can create a selection by clicking and dragging the pointer over a
portion of code, or by double-clicking to highlight the word or line under the pointer
(the Double click line option determines whether a word or line highlights). You may
also press Ctrl + A to select all text. You can cut, copy, paste, and print selections.

Enable dragging: Select to permit dragging and dropping a selection to reposition
it in the code. This option works only if you also select Enable selection.

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.

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).
