Mastering keyboard shortcuts can dramatically improve your efficiency as a developer. By reducing dependency on the mouse, you can navigate, edit, and manage your workflow faster. Here are ten essential shortcuts every developer should know:
1. Duplicate a Line of Code
Need to copy a line of code quickly? Use Ctrl + D (Cmd + D on Mac) in many text editors to duplicate a line without the hassle of copy-pasting.

To quickly toggle comments for a selected block of code, use Ctrl + / (Cmd + / on Mac). This is a universal shortcut across most IDEs.
3. Navigate Between Open Files
Switch between open files in your editor using Ctrl + Tab (Cmd + Tab on Mac). It’s a faster way to move around without touching the mouse.
4. Move Lines Up or Down
Rearrange your code effortlessly by selecting a line and pressing Alt + Up/Down Arrow (Option + Up/Down Arrow on Mac) to move it.
5. Find and Replace
To locate and replace text, use Ctrl + H (Cmd + H on Mac). This shortcut saves time when making widespread changes.
6. Go to Definition

7. Multi-Cursor Editing
Edit multiple lines simultaneously by holding Alt (Option on Mac) and clicking to add cursors in different locations.

Open your IDE’s terminal directly with Ctrl + (Cmd + on Mac). No need to switch windows to access the command line.
9. Format Code
Ensure your code looks clean and consistent with Shift + Alt + F (Shift + Option + F on Mac). This applies the editor’s default formatting rules.

Undo changes with Ctrl + Z (Cmd + Z on Mac) and redo them with Ctrl + Shift + Z (Cmd + Shift + Z on Mac). These are your ultimate lifesavers!
