KDevelop Keyboard Shortcuts: The Complete List
Quick answer: The most-used KDevelop shortcuts are Ctrl+Alt+O (Quick Open file), Ctrl+. and Ctrl+, (jump to declaration/definition), Ctrl+D (comment out code), F9/F10/F11/F12 (debugger run/step), and F8 (build). KDevelop is built on the KDE/Kate editor framework, so it also uses all the standard KDE editing shortcuts, and almost every shortcut is fully remappable under Settings → Configure Keyboard Shortcuts.
KDevelop is a free, open-source integrated development environment (IDE) maintained by the KDE community, built on the Qt framework and the KTextEditor (Kate) editing engine. It is most commonly used for C, C++, Python, and PHP development on Linux, with builds also available for Windows and macOS. Because it inherits Kate’s editor, many of its shortcuts match other KDE applications, while its navigation, refactoring, and debugging keys are specific to the IDE.
This guide lists the verified default shortcuts, organized by task, and shows you how to view or change any of them inside KDevelop. A free downloadable PDF cheat sheet is linked at the bottom.

Debugging Shortcuts
KDevelop maps the common debugger actions onto a single block of function keys so they’re easy to memorize. These bindings come from KDevelop’s own development history.
| Action | Shortcut |
|---|---|
| Run / Continue in debugger | F9 |
| Step over | F10 |
| Step into | F11 |
| Step out | F12 |
| Start Debug Launch | Alt + F9 |
| Toggle breakpoint | (no default — set via Run menu or right-click) |
How to Customize KDevelop Shortcuts
Every shortcut in KDevelop can be changed, and you can also build your own scheme from scratch.
- Open Settings → Configure Keyboard Shortcuts.
- Type part of an action name in the search box at the top to filter the list.
- Click the action, then press the key combination you want to assign.
- If the combination is already in use, KDevelop warns you and lets you reassign it.
- To start clean, click Details → New to create a fresh scheme; you can switch between schemes for reference.
Two popular customizations from the KDE community: bind Align to Tab so the editor auto-indents code for you, and move Toggle Breakpoint onto Ctrl+B since it’s used so often.

KDevelop Shortcuts on Linux, Windows & macOS
KDevelop runs primarily on Linux but ships for Windows and macOS too. The shortcuts are the same across platforms with one substitution: on macOS, the Ctrl key in these tables generally maps to Command (⌘), following standard Qt/macOS conventions. Function keys (F8–F12) behave the same everywhere, though on some Mac keyboards you may need to hold fn to send a raw function key.
| Platform | Modifier behavior |
|---|---|
| Linux | Ctrl, Alt, Shift as listed |
| Windows | Ctrl, Alt, Shift as listed |
| macOS | Ctrl → ⌘ (Command); function keys may need fn |

Final Thoughts
Mastering these shortcuts turns KDevelop from a capable editor into a fast, keyboard-driven IDE the Quick Open and jump-to-declaration keys alone save hundreds of mouse trips a day on a large C or C++ codebase. Start with the handful you’ll use constantly (Ctrl+Alt+O, Ctrl+., Ctrl+,, Ctrl+D, and the F9–F12 debugger block), then layer in the rest as they become muscle memory.
And remember that none of these are fixed: everything is remappable under Settings → Configure Keyboard Shortcuts, so if a binding fights your workflow or conflicts with another action, reassign it in seconds.
