Set meta/command/⌘ key as Launchpad shortcut?

Question

I would like to set the command key ⌘ as the shortcut to open Launchpad, is that possible? I've tried in the System Preferences, but it won't let me.

Answer 1

To make this work you have to use a third party tool: Karabiner.

In the customized keycode below I assume that you haven't enabled the consumer key function in System Preferences but have to access the consumer keys by using the fn+F1...F12.

In the example below just the left command key launches Launchpad if hit once. A second hit will close Launchpad again.

You can use either the left or the right command key as usual otherwise (e.g. open files with cmd+O or print cmd+P)

1. Download, install and open Karabiner
2. Open in the menulet Karabiner -> Preferences
3. Open the tab Misc & Uninstall
4. Hit the button Open private.xml
5. Open the file private.xml with an appropriate editor

6. Enter the customized keycode

   <?xml version="1.0"?>
   <root>
       <item>
           <name>When you type Command_L only, start Launchpad</name>
           <appendix>(Change Command_L lazy start Launchpad)</appendix>
           <identifier>remap.command_l_lazy_to_launchpad</identifier>
           <autogen>__KeyOverlaidModifier__ KeyCode::COMMAND_L, KeyCode::VK_LAZY_COMMAND_L, KeyCode::LAUNCHPAD, ModifierFlag::FN</autogen>
       </item>
   </root>
   

7. Save the file

8. Open in the menulet Karabiner -> Preferences the tab Change Key
9. Hit the ReloadXML button
10. Enable the remapping. It should be listed at the beginning.
