Beyond Compare Keyboard Shortcuts
Beyond Compare's shortcut set is organized around jumping between differences rather than general editing, since the app's entire purpose is highlighting what changed between two files or folders and letting you act on those specific spots quickly. Next/previous difference navigation (Alt+Down / Alt+Up in the default scheme) is the single most-used pair of shortcuts in any real session, since scrolling manually through a long diff looking for changes defeats the point of using a comparison tool at all. Beyond Compare also distinguishes between folder-level shortcuts (used when comparing two directory trees) and file-level shortcuts (used once you've drilled into an actual text diff), and which set is active depends entirely on which pane has focus — a folder-compare view and an open text-diff tab respond to a meaningfully different set of keys even within the same session. Enterprise software teams doing careful code reviews before a merge, and system administrators auditing configuration drift between two servers' file trees, are Beyond Compare's most committed users, since its combination of speed, accuracy, and support for binary and image comparison (not just text) goes well beyond what a free alternative like WinMerge or the command-line diff utility offers — that extra capability is exactly what justifies its price for teams doing this kind of comparison work as a core, recurring part of their job rather than an occasional convenience.
Difference Navigation
| Action | Windows | Mac | Description |
|---|---|---|---|
| Go to next difference | Alt+Down | Option+Down | Jumps the view to the next detected difference in the comparison, the core navigation habit for working through a diff of any meaningful length. |
| Go to previous difference | Alt+Up | Option+Up | Jumps back to the previous difference, used alongside next-difference to step through changes in either direction without scrolling manually. |
| Go to next unresolved conflict | Alt+Shift+Down | Option+Shift+Down | In a three-way merge, jumps specifically to the next conflict requiring manual resolution, skipping over differences that were already auto-merged cleanly. |
| Toggle synchronized scrolling | Ctrl+Shift+S (varies) | Cmd+Shift+S | Toggles whether scrolling one pane automatically scrolls the other pane to the corresponding position, useful to disable temporarily when you need to inspect one side independently without the other pane jumping along with it. |
Merge Actions
| Action | Windows | Mac | Description |
|---|---|---|---|
| Copy selected difference to right file | Ctrl+Alt+Right | Cmd+Option+Right | Copies the currently focused difference block from the left file into the right file, one half of Beyond Compare's core two-way merge action pair. |
| Copy selected difference to left file | Ctrl+Alt+Left | Cmd+Option+Left | Takes whichever difference block currently has focus on the right pane and overwrites the corresponding block on the left with it, the reverse direction of the right-side copy command. |
| Save current file | Ctrl+S | Cmd+S | Saves changes made to the currently focused file pane, standard convention shared with virtually all text-editing software. |
| Manually align two lines | Ctrl+Alt+A (varies) | Cmd+Option+A | Forces a specific line in the left pane to align with a specific line in the right pane, useful when Beyond Compare's automatic alignment algorithm misjudges where two blocks of inserted or deleted lines actually correspond to each other. |
Folder Compare
| Action | Windows | Mac | Description |
|---|---|---|---|
| Expand folder in comparison tree | Right Arrow (on folder row) | Right Arrow | Expands a collapsed folder in the folder-comparison tree view to show its contents and their individual comparison status. |
| Show only differing items | Ctrl+D | Cmd+D | Filters the folder comparison view to show only items that actually differ, hiding identical files so large trees with mostly-matching content are easier to scan for the parts that matter. |
| Open saved comparison session | Ctrl+O | Cmd+O | Reopens a previously saved comparison session (the specific pair of files or folders along with your filter and view settings), letting you resume an ongoing review without reconfiguring everything from scratch. |
Frequently Asked Questions
Do the same shortcuts work whether I'm comparing two files or two folders?
Not entirely — difference-navigation shortcuts (next/previous difference) apply in both contexts but jump between different units (differing lines within a file versus differing files within a folder tree), while some folder-specific shortcuts like filtering to show only differing items only make sense in folder-compare view and have no equivalent inside a single text-file diff.
What happens if I use copy-to-right on a difference during a three-way merge?
In two-way comparisons, copy-to-right/left directly overwrites the target side with the source side's content for that difference block. In a three-way merge, Beyond Compare instead resolves that specific conflict by choosing which source's version to keep for the merged output, without necessarily overwriting either original input file.
Can Beyond Compare shortcuts be customized?
Yes, through Tools > Preferences > Keyboard, where nearly every command has an assignable shortcut, and Beyond Compare also ships alternate preset keymaps (including ones mimicking other diff tools) for users switching from a different comparison utility.
Does Beyond Compare support comparing images or only text-based files?
Yes — Beyond Compare includes a dedicated image comparison mode with options like overlay difference highlighting, side-by-side, and blink comparison, which is a meaningful differentiator from free text-only diff tools and is commonly used by developers comparing rendered UI screenshots or designers checking asset revisions.
Can Beyond Compare integrate with version control systems like Git or SVN?
Yes, it's commonly configured as the external diff and merge tool for Git, SVN, Mercurial, and other version control systems, similar to how WinMerge is often set up, letting you run comparisons and resolve merge conflicts through Beyond Compare's richer interface rather than a command-line diff output.
Why does a folder comparison sometimes show a file as 'orphan' rather than simply different?
An orphan file exists on only one side of the comparison with no corresponding file on the other side at all, which is a distinct state from a file that exists on both sides but has different content — Beyond Compare's folder view color-codes and labels these differently so you can quickly distinguish 'this file is missing entirely from one side' from 'this file exists on both sides but changed.'
Is Beyond Compare available on all three major desktop platforms with the same shortcut set?
Yes — Beyond Compare ships native versions for Windows, Mac, and Linux, and while the modifier keys follow each platform's own convention (Ctrl on Windows/Linux, Cmd/Option on Mac), the underlying command set and overall workflow stay consistent, making it one of the more genuinely cross-platform-consistent comparison tools available.
Can Beyond Compare compare the contents of ZIP files without extracting them first?
Yes — Beyond Compare can browse into common archive formats and compare their contents directly, treating them similarly to regular folders for comparison purposes, which is a convenience several free alternatives either lack entirely or require a separate plugin to achieve.
Does Beyond Compare have a shortcut for syncing two folders after reviewing differences?
Yes — once a folder comparison highlights differences, selecting the files or folders you want to sync and choosing the copy direction (left-to-right or right-to-left arrows in the toolbar) applies that specific sync action; there's no single global shortcut for an unattended full sync, since Beyond Compare deliberately keeps sync actions reviewable rather than automatic to avoid accidentally overwriting the wrong side.
