Tooltip and Shortcut


the Previous Difference button/the Next Difference button

Previous Difference / Next Difference Shift+F7 F7

Use these buttons to jump to the next/previous difference.

When the last/first difference is reached, PyCharm suggests to click the arrow buttons F7/Shift+F7 once more and compare other files, depending on the Go to the next file after reaching last change option in the Differences Viewer settings.

This behavior is supported only when the Differences Viewer is invoked from the Version Control tool window Alt+9 .


Compare Previous/Next File

Click these buttons to compare the local copy of the previous/next file with its update from the server.

the Edit button

Jump to Source

Click this button to open the selected file in the active pane in the editor. The caret will be placed in the same position as in the Differences Viewer.

Viewer type

Use this list to choose a viewer type. The side-by-side viewer has two panels; the unified viewer has one panel only.

Both types of viewers enable you to

  • Edit code. Note that one can change text only in the right-hand part of the default viewer, or, in case of the unified viewer, in the lower ("after") line, that is in your local version of the file.

  • Perform the Apply/Append/Revert actions.


Use this list to define how the differences viewer should treat whitespaces.

  • Do not ignore: white spaces are important, and all differences are highlighted. This option is selected by default.

  • Trim whitespaces: ("\t", " "), if they appear in the end and in the beginning of a line.

    • If two lines differ in trailing whitespaces only, these lines are considered equal.

    • If two lines are different, such trailing whitespaces are not highlighted in the By word mode.

  • Ignore whitespaces: white spaces are not important, regardless of their location in the source code.

  • Ignore whitespaces and empty lines: the following entities are ignored:

    • all whitespaces (as in the 'Ignore whitespaces' option)

    • all added or removed lines consisting of whitespaces only

    • all changes consisting of splitting or joining lines without changes to non-whitespace parts.
      For example, changing a b c to a \n b c is not highlighted in this mode.

Highlighting mode

Select the way differences granularity is highlighted.

The available options are:

  • Highlight words: the modified words are highlighted

  • Highlight lines: the modified lines are highlighted

  • Highlight split changes: if this option is selected, big changes are split into smaller 'atomic' changes.
    For example, A \n B vs. A X \n B X will be treated as two changes instead of one.

  • Highlight symbols: the modified symbols will be highlighted

  • Do not highlight: if this option is selected, the differences are not highlighted at all. This option is intended for significantly modified files, where highlighting only introduces additional difficulties.

the Collapse All button

Collapse unchanged fragments

Click this button to collapse all unchanged fragments in both files. The amount of non-collapsible unchanged lines is configurable in the Diff & Merge settings page.

Synchronize scrolling

Synchronize scrolling

Click this button to scroll both differences panes simultaneously. If this button is released, each pane can be scrolled independently.

disable editing

Disable editing

Click this button to enable editing of the local copy of the selected file, which is disabled by default. When editing is enabled, you can make last-minute changes to the modified file before committing it.

the Gear icon

Editor settings

Click this button to open a list of available options. Select or clear these options to show or hide line numbers, indentation guides, white spaces, and soft wraps.

the External Tools icon

Show diff in external tool

Click this button to invoke an external differences viewer, specified in the External Diff Tools settings page.

This button only appears on the toolbar when the Use external diff tool option is enabled in the External Diff Tools settings page.

the Help button


Click this button to show the corresponding help page.

Note that the options listed above are available for text files only. PyCharm cannot compare binary files, so most commands will be unavailable for them.

After you've selected the files you want to commit, click the Create Patch button and specify the patch file options in the dialog that opens.
