What is the shortcut in IntelliJ IDEA to move across or select individual words of a camelized word? Lets say I have aLongMultiWordVariableName, I want to be able to move the cursor to each word for editing or select parts of the variable.
Eclipse has a shortcut to do this Ctrl+←/→ for move and Ctrl+Shift+←/→ for selection.
IDEA has the same keystrokes as Eclipse for camel-case words, but you have to have the CamelHumps option turned on (it's in Settings -> Editor -> General -> Smart Keys -> Use "CamelHumps" words )
Yes, the answer of yalestar is correct. Settings > Editor > Smart keys > Use "CamelHumps" words
However, here is something that can be usefull to know: If you want to be able to select the whole word by double-click on it, unselect the "Honor 'CamelHumps' words settings when selecting on double click" in Settings > Editor.
There is a shortcut in latest version of Android Studio. You can just tap "Shift" key twice(double click) and then in search type "camelhum" then the option will appear and you can toggle it on/off. I have attached an image for reference.
