Mac uses Karabiner to configure keyboard mapping

The effect after configuration:

Applicable system:

 

command_left+space : 触发IDEA search everywhere

space+command_left:触发IDEA search everywhere

option_left+space: trigger to open Google browser

space+option_left: trigger to open Google browser

Press option_left alone: ​​trigger IDEA to find the interface

Press control_left alone: ​​trigger switch window

Press command_right alone: ​​open Alfred

Press caps lock alone: ​​trigger escape
