TLDR

To manipulate comments in Eclipse promptly:

  • Toggle line comment:
    • Ctrl + / (Windows/Linux)
    • Cmd + / (macOS)
  • Block comment:
    • Add: Ctrl + Shift + /
    • Remove: Ctrl + Shift + **

For individual lines, no selection is required:

  • Before: System.out.println("Active"); // So full of life
  • After: // System.out.println("Commented"); // It's quieter here

For blocks of text, select first:

  • Before: /* Your selected dialogue starts... */
  • After: /*...And ends. You're now on mute! */

Turbocharging your coding with shortcuts

Shortcuts for every context

Eclipse provides additional key combinations for distinct circumstances:

  • Toggle comments on several lines with Ctrl + 7, blurring the line between adding or removing comments.
  • Use Ctrl + Shift + C as a universal switch for Java and XHTML files to manage comments seamlessly.
  • If XHTML is your playground, rely on Ctrl + Shift + C for a smooth single-line comment operation.

Keyboard shortcuts for a productivity leap

Incorporating shortcuts into your coding toolbox isn't just about saving time:

  • Boost your coding speed: Manipulate comments without switching between the keyboard and navigating menus.
  • Streamline testing: Swiftly enable or disable code blocks for effective debugging or testing.
  • Fixate on your core task: Keep your focus locked in by avoiding mouse-induced distractions.

Enhancing productivity with shortcuts

Here are some scenarios where Eclipse shortcuts can supercharge your coding:

  • Efficient Debugging: Toggle print statements or debug lines—like a coder with superpowers.
  • Clean code maintenance: Keep the readability of your codebase intact by hiding your little secret experiments.
  • Collaborative coding: Make code reviews or pair programming a breeze with smart comment manipulation.

Aligning with Eclipse's coding philosophy

These shortcuts underline the central philosophy of Eclipse—efficiency:

  • Consistent Coding Practices: Adopt a shortcut-centric development approach—because why spend time on the mundane?
  • Command the IDE: Match key bindings with personal workflow. Go to Window > Preferences > General > Keys and make it your way.
  • Harnessing plugins: Consider plugins like Eclipse Code Formatter for an automatic rule-based commenting.

Maximizing the local history feature

Eclipse's local history feature fishnets your comment changes over time:

  • Keep track of your changes, the bloopers, and the brilliant saves.
  • Undo unwanted comment or uncomment actions—because even coders need an oops button!

Eclipse vs. other IDEs

Coming from another IDE like Intellij IDEA? Embrace Eclipse's unique keyboard system:

  • Map Eclipse shortcuts with other IDEs—imagine it as learning a new coding dialect.
  • Commenting shortcuts—one of many reasons to love Eclipse!
