What are the most useful Intellij IDEA keyboard shortcuts? [closed]

Answer 1

One of my real favorites may not count as a keyboard shortcut exactly. But the "iter" smart template is really great.

basically if you want to iterate though something using a for loop type "iter" then tab to use the live template

itertab

it will figure out the most likely variable you want to iterate over and generate a for loop for it. I'm pretty sure it uses the nearest reference to an object which supports iteration.

Help\Productivity Guide

It tells you what are the shortcuts you use/don't use and displays usage statistics. It will guide you to the unknown features.

Answer 3

Shift+Delete deletes the entire line (will 'cut' it to clipboard)

Ctrl+Alt+L to reformat and optimize imports

Ctrl+Shift+J to join lines (pull content of next line up to current line).

Answer 4

This is probably dependent on your development environment, but when doing BlackBerry development I code in IntelliJ and still compile and debug through the BlackBerry JDE. Ctrl + Shift + C is vital in this case as it allows you to copy the full path of the file you are currently editing, making it easy to open the file in the separate dev environment.

Answer 5

By far my favourite all purpose shortcut is Ctrl+Shift+A

It does a search as you type through all the commands in intellij. Not only that but when you find the command you want it also displays the corresponding shortcut key next to it!

Answer 6

Try using the Key Promoter plugin. That will help in learning the shortcuts. Couple of shortcuts apart from the above suggestions:

• Alt + Ins: Works consistently to insert anything. (Add a new class, method etc)
• Ctrl + Alt + T: Surround code block. Another useful stuff.
