# What is the comment shortcut?

I went to a Wolfram Technologies workshop a few weeks ago and the presenter showed us a keyboard shortcut that when a block of input is selected, the shortcut puts the block of selected input in (* comment *) brackets. I've forgotten what the shortcut is though. Does anyone know what it is?

The short-cut keys for various actions can usually be found directly in the menu. Here on OS X you see the +/ at the right side under Un/Comment Selection:

As pointed out in the comments for various systems the short-cuts to comment a selection are

• +/

### Windows

• Alt+/
• Right click + u which uses the context menu short-cut

### Linux

• Alt+/
• Alt+Shift+7 on a German keyboard
• Unfortunately on a german keyboard it's impossible to get [Alt]+[/]. It behaves like [Alt]+[7] and you'll change the style to "Text". But somewhere on SE there is a solution for mapping the commands to other keys. – Phab Oct 23 '14 at 9:17
• @Phab: can you tell where on SE I can find this? – riddleculous Feb 24 '17 at 11:09
• @riddleculous Have a look at these SE topics: Link1, Link2 and Link3. With this information I changed a lot of my shortcuts. – Phab Feb 28 '17 at 7:03
• @Phab: Why not simply use [Alt]+[Shift]+[/]. For me it works even with the German keyboard layout. – Display Name Feb 8 '18 at 12:14
