"enter" key not working anymore

shift + enter does work so I can use Intellij again but a single enter does nothing.

Hmmmmm, tab is not working either. Seeing as the forum isn't filling up with people having the same problem it's probably not the update that did it.

Hopefully someone can tell me what setting I accidentily (as I haven't fiddled with the settings in the days before the problem occured) flicked.

I bought the Ultimate 12 version and was doing the 30 day trial for the 13 when this occured. I read a post that said that 12 keys were disabled for the trial so I figured that was the problem. Just bought my upgrade and entered the new key but the problem persists.

Python plugin did an update, after restart everything worked again. Not sure if related, probably not but problem solved.

I rebooted and restarted before that also.

Back to work :)

I've had same issue with Rubymine since last year. It's only been once a day kind of thing. Lately, it's happening way too often.

I am on version 8.0 (build: 143.381)

Same problem here (IntelliJ Ce 2017.1.2 on Mac OS 10.12.4). Restart and reboot didn't help.

I had the same problem, but in fact it was a change I tried to do in the keymap.

Solution for me was to reset the keymap to defaults

Press the "Insert" key. 

Pressionando a tecla Insert/PrtSc dá certo

Entering “Insert” key worked for me. Thank you!
