|Prefer moving caret line to minimize editor scrolling||Click this option to choose moving the caret. When you step through the lines of code during the debugging session, the caret moves down, and the editor canvas doesn't scroll until the caret line reaches the bottom of the screen.|
|Maximum number of contents to keep in clipboard||In this text box, specify how many code blocks can be kept in clipboard.|
|Recent file limit||In this text box, specify how many file names can be included in the list of recent files.|

|Ensure line feed at file end on Save||Select this check box to have PyCharm automatically add an empty line in the end of a file during the save procedure.|
|Use soft wraps in the editor||
If this check box is selected, the soft wraps (or word wraps) are used in the editor.
Horizontal scroll bar in general is not shown, when this option is enabled. However, in certain cases, when a line cannot be "soft-wrapped", the horizontal scroll bar still appears (for example, a line consists of a single string that is wider than the visible area.)

|Use custom soft wrap indent||
Select this check box to use custom indentation for soft wraps on resizing the editor.
Specify the indent value in the text field to the right.
This field is only available when at least one of the Use soft wraps... check boxes is selected.
|Show all soft wraps||If this check box is selected, the soft wrap characters
will be always shown
at the end of each line, and at the beginning of each next line.
Otherwise, the soft wrap characters will be shown in the active logical line only.
|Allow placement of caret after end of line||If this check box is cleared, the caret never rests after the last symbol in a line.|
|Allow placement of caret inside tabs||Select this check box to allow placing the caret inside tab characters. The reason is that each tab character shows in the editor as a set of 'virtual' space characters.|
|Show virtual space at file bottom||If this check box is selected, the currently edited line (even if it is the final line) can be scrolled to the top of the screen. PyCharm adds the necessary amount of virtual lines.|
|Highlight on Caret Movement|
|Highlight matched brace||Select this check box to have PyCharm highlight pairs of opening/closing braces when you position the caret right before the opening or right after the closing one. It also works for HTML and XML tags.|
|Highlight current scope||Select this check box to have PyCharm highlight the available scope for the code typed in the current caret location.|
|Highlight usages of element at caret||Select this check box to have PyCharm highlight all usages of the element at which the caret is currently positioned.|
|Show "Reformat Code" dialog||If this check box is selected, the Reformat Code dialog box will appear every time you try to reformat code, where you can specify the scope of reformatting. Otherwise, PyCharm will reformat code silently.|
|Show "Optimize Imports" dialog||If this check box is selected, the Optimize Imports dialog box will appear every time you try to optimize import statements. Otherwise, PyCharm will optimize imports silently.|
|Enable in-place mode||
Select or clear this check box to enable or disable in-place refactorings for Python.
The in-place in connection with the refactorings means specifying all or most of the information necessary for the refactoring by typing, right in the editor. All the affected code fragments are highlighted and change as you type. If appropriate, additional refactoring options are selected in corresponding option boxes.
The in-place refactoring mode is available for the following refactorings:
If this check box is not selected, the refactoring settings for all of the refactorings are specified in the corresponding dialogs.
