Eclipse ctrl+right does nothing

Eclipse's welcome screen causes this kind of bug in the editor specifically (https://bugs.eclipse.org/bugs/show_bug.cgi?id=426557). Sometimes you can find that when you restart can't move with control+arrow in the editor but you can in other views like console window.

You can disable welcome screen ( in most eclipse based IDEs it's a checkbox in the welcome screen ) and then restart eclipse just to be sure it won't happend again. Everything will work again.

I had an issue just like this with Eclipse Neon. I was baffled by answers I was finding about the welcome screen, but I disabled it, and apparently that was causing the issue, because Ctrl+Shift+Right/Left worked, after disabling it. In Neon, the welcome screen has an "Always show Welcome at startup" box you can uncheck, in the lower right corner of the welcome screen when it appears. After unchecking it, selecting words worked, again. Somehow.

This issue is caused by the welcome screen. Uncheck the "Always show..." checkbox on you welcome screen.

If welcome screen of your eclipse distribution does not have the "Always show..." checkbox, then another option to disable welcome screen is to create file in your workspace:

.metadata\.plugins\org.eclipse.ui.intro\introstate

and insert following content:

<?xml version="1.0" encoding="UTF-8"?>
<state reopen="false"/>

I've got the same problem with Eclipse-Oxygen and disabling the welcome screen fixed the issue. I gave this answer just to confirm the solutions explained above also work for the following eclipse version;

1: Eclipse-Oxygen Version: Oxygen.1a Release (4.7.1a) (released on October 2017)

2: Version: Oxygen.3a Release (4.7.3a) Build id: 20180405-1200

On ubuntu 16.4 Welcome screen is blank and there is no way to disable it. Installing libwebkitgtk-3.0-0 as suggested on eclipse site work just partially and no check box are showed.

Last resource: find where are your plugin directory and remove

org.eclipse.ui.intro.universal_3.3.0.v20160519-1604.jar

In my installation was at

~/.p2/pool/plugins/org.eclipse.ui.intro.universal_3.3.0.v20160519-1604.jar

Just a note: in the last 4/5 years Eclipse's bugs was raising very fast :( ....
