Use the General page of the Settings dialog to configure the editor behaviour and customize its view.
Change font size with Ctrl/Command+Mouse Wheel
Enable this option to be able to change font size in the editor by rolling the mouse wheel while holding the Ctrl key.
Select Active editor to change font size only in the current editor tab. If you close and reopen the document, the font size will be reset to the default font or to the color scheme font according to your settings.
Select All editors to change font size in all editor tabs. When you change the font size this way, the new font size is saved in the current color scheme and will apply to all open documents as well as to the newly opened ones. If necessary, you can change it on the Editor | Color Scheme | Color Scheme Font page of the IDE settings Ctrl+Alt+S.
If this checkbox is selected, you can drag-and-drop code fragments in the editor.
Soft-wrap these files
Use this field to apply soft wraps to specific file types (For example, it might be helpful when you are writing documentation in markdown files). Enter file extensions separating them with semicolon.
You can also enable or disable soft wraps right in the editor:
Right-click the left gutter and from the context menu, either select or clear the Soft-Wrap Current Editor option. Keep in mind that these settings affect only the current editor, not a file.
To quickly access the settings, select Configure Soft Wraps from the list of options.
Use the original line's indent for wrapped fragments
Select this checkbox to use custom indentation for soft wraps on resizing the editor or console. Use the Add additional indent field to specify the indent number.
Only show soft-wrap indicators for the current line
If this checkbox is selected, the soft wrap characters will be shown in the active logical line only.
Otherwise, soft wraps characters will be shown at the end of each line, and at the beginning of each next line.
Allow caret placement
After the end of line: if this checkbox is selected, you will be able to set your caret anywhere after the last character in any line. As soon as you start typing at a position beyond the end of the line, the necessary number of spaces will be added between the end of the line and the beginning of your input.
Inside tabs: select this checkbox 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 the bottom of the file
If this checkbox 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.
When moving by words
Use this list to configure where the caret should stop when moved by words. You can select from the following options:
Jump to current word boundaries: this is the default option. When you move the caret forward (Ctrl+Right), PyCharm places it to the end of the current word.
When you move the caret to the previous word (Ctrl+Left), PyCharm places the caret at the beginning of the current word.
Always jump to word start: when you select this option, the caret always moves to the beginning of the word.
Always jump to word end: when you select this option, the caret always moves to the end of the word.
Jump to next/previous word boundaries: when you select this option, the caret moves forward to the start of the next word, and when moved backwards, the caret jumps to the end of the previous word.
Stop at both word boundaries: when you select this option, the caret stops at both the start and the end of each word.
Upon line break
Use this list to configure where the caret should stop on line breaks. You can select from the following options:
Jump to next/previous line boundaries: when you select this option, the caret moves forward to the beginning of the next line, and when moved backwards, the caret jumps to the end of the previous line.
Ignore line breaks: when you select this option, PyCharm ignores the line breaks, and the caret moves according to the configuration specified in the Moving by words list.
Stop at both line boundaries: when you select this option, the caret stops at both the start and the end of each line.
Jump to current line boundaries: when you select this option, the caret always jumps to the end of the current line (when moved forward) or to the beginning of the current line (when moved backwards).
Check the following example when you have Always jump to word start specified in the Moving by words list and Jump to current line boundaries specified in the Upon line break list:
Always jump to line start: when you select this option, the caret always moves to the start of a line.
Always jump to line end: when you select this option, the caret always moves to the end of a line.
Enable smooth scrolling
If this option is enabled, the editor scrolls the page when you navigate to an element, instead of just jumping to the target location.
Keep the caret in place, scroll editor canvas: select this option to choose scrolling editor canvas and keeping the caret at place.
This can be helpful in course of debugging session. As you step through the lines of code, the editor canvas scrolls, while the line at caret is always in the center of the screen.
Move caret, 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.
Copy (Ctrl+C) as rich text
Select this checkbox to copy a rich text from the editor to any other editor that recognizes RTF. Otherwise, the IDE copies a plain text.
Color scheme for copied fragment
Use this list to select a color scheme for the text copy. You can select from the following options:
Remove trailing spaces on
Select the mode in which PyCharm will handle trailing spaces at the end of lines on file saving:
Modified lines: strips trailing spaces only in the end of modified lines.
All lines: strips trailing spaces in all lines.
Keep trailing spaces on caret line
If this option is unselected, trailing spaces will be stripped on the line where the caret is placed on save operation.
Remove trailing blank lines at the end of saved files
If this checkbox is unselected, PyCharm will keep the trailing blank lines on saving files.
Ensure every saved file ends with a line break
Select this checkbox to have PyCharm automatically add an empty line in the end of a file during the save procedure.
