Commenting blocks in Eclipse on Mac

Question

How do I comment blocks of code in Eclipse on a Mac?

Solution 1

Command (the clover/apple key next to the space bar) forward slash (/)

Solution 2

Apple + Shift + / will toggle a block of selected code using /* */
Apple + / will toggle a line (or multiple, if selected) using //

You may have to disable the OS hotkey (apple + shift + / brings up the help menu)

Solution 3

Ctrl + cmd + / <- block comment and Ctrol + cmd + \ <- remove comment

Solution 4

Command + / comments the selection.

How to disable the OS hotkey in Mac ?

[Firas]

@user1182253 Goto your Mac Settings application -> Keyboard -> Shortcuts/Hot Keys -> Applications shorcuts -> disable "show help menu" Sorry if there are some mistakes in the menu labels, my mac os is not in english.

Unfortunately, even with this, it won't work for xml code comments/uncomments.

Thank you! Just started using Android studio and I use Cmd + Shift + / in every other editor for comments, but this was just bringing up the help menu.

@Marcus, I believe you cannot use /* */ style comments for XML. You should use <!-- --> style instead.

[Marcus]

@briggsm Right, my only point is that there aren't shortcuts for commenting blocks in xml.

For me on Yosemite, on STS 3.6.4, the keys for block comments are Cmd + Ctrl + /

It appears this has been changed to avoid conflict with the help shortcut in OSX, and the answer is now, as @PawelPros noted below, ctrl+command+/ to comment, ctrl+command+\ to uncomment.
