IntelliJ idea for Mac shortcut keys

• According to the official PDF translation: Https://www.jetbrains.com/idea/docs/IntelliJIDEA_ReferenceCard_Mac.pdf
• In IntelliJ idea there are two Mac versions of the shortcut keys, one called: Mac OS X, one called: Mac OS X 10.5+
• Currently used: Mac OS X 10.5+
• There are two sets of reasons: https://intellij-support.jetbrains.com/hc/en-us/community/posts/206159109-Updated-Mac-OS-X-keymap-Feedback-needed

It is recommended that you cancel or change the shortcut keys in your MAC system that conflict with IntelliJ idea, and do not recommend changing the default shortcut key for IntelliJ.
