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:

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.

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