If you’re a Java developer, I’m sure you’ve used the IDEA compiler, but I’m not going to mention it here. I came from Eclipse. In order to better use this IDE, master the shortcut keys must be indispensable, below to list all the idea shortcut keys for everyone to collect, I commonly used shortcut keys have been marked in bold, for reference only.
Note: If there is no effect after clicking the shortcut key, you can check whether it conflicts with QQ, Sogou input method and other software shortcut keys.
