I want to map CapsLock to Left Mouse Button using Karabiner Elements in macOS Sierra.
I used to have such mapping in previous OS X versions using Seil and Karabiner but those no longer work in Sierra.
I tried to guess what should I put in the configuration JSON but failed.
"simple_modifications" : {
"caps_lock" : WHAT_SHOULD_I_PUT_HERE?
},
Is it even possible to map Caps Lock to Left Mouse button in Karabiner Elements?
I don't have a multi-button mouse to test with, but it should support mapping gestures to arbitrary buttons.
Use Seil to map caps lock to some key like F19. Then install Karabiner and save a file like this as ~/Library/Application Support/Karabiner/private.xml:
<?xml version="1.0"?>
<root>
<item>
<name>custom</name>
<identifier>custom</identifier>
<autogen>__KeyToKey__ KeyCode::F19, ModifierFlag::NONE, KeyCode::KEY_9, ModifierFlag::SHIFT_L</autogen>
<autogen>__KeyToKey__ KeyCode::F19, VK_SHIFT, KeyCode::KEY_0, ModifierFlag::SHIFT_L</autogen>
</item>
</root>
Then open the Karabiner application, press the ReloadXML button, and click the checkbox for the setting.
If others search for how to for example map pressing caps lock to escape and holding caps lock to control, use KeyOverlaidModifier:
__KeyOverlaidModifier__ KeyCode::F19, KeyCode::CONTROL_L, KeyCode::ESCAPE

BUT: it's actually quite simple (if I didn't mis-interpret your question):
Just select [Add item] in K.-Element's "Simple Modifications" tab, choose "caps_lock" (left) and "button1" (right) – and you're DONE!
… no need for "Complex Modifications", btw.
