IntelliJ autocomplete to replace the function name

问题

I've switched from Eclipse to IntelliJ and there is something which I couldn't find yet nor google:

How to get the autocomplete to replace the name of the function? In Eclipse, it would be the ctrl+enter functionality.

For example,

userController.setAmount();

suppose I would like not to call the setAmount() but a setDefaultPassword(), I place my caret after the set then ctrl+space to autocomplete, the setDefaultPassword() shows up but if I press enter, it won't replace Amount() and I'll end up with

userController.setDefaultPassword();Amount();

So obviously what I wanted is to replace the setAmount() by setDefaultPassword().

Press Tab instead of Enter to select the item, and the identifier will be replaced. See also http://jetbrains.dzone.com/articles/top-20-code-completions-in-intellij-idea

回答2:

You can configure it in IntelliJ IDEA Settings under Keymap / Editor Actions / Choose Lookup Item Replace.

Not a solution, but a workaround:

1. place the cursor after set
2. press ctrl + shift + cursor-right. So the characters after set are selected.
3. press ctrl + blank
4. select a proposal and press enter
