Shortcuts not working in Eclipse Neon

Question

I'm running Eclipse Version: Neon.2 Release (4.6.2) on Windows 10.

Certain shortcuts like ctrl+backspace (which should delete the previous word) aren't working.

Under preferances > General > keys the setting is set as follows:

+----------+--------------------------+
| Command  | Delete the previous word |
+----------+--------------------------+
| Binding  | Ctrl+Backspace           |
+----------+--------------------------+
| When     | Editing Text             |
+----------+--------------------------+
| Category | Text Editing             |
+----------+--------------------------+
| User     | U                        |
+----------+--------------------------+

Answer 1

I was finding about the welcome screen, but I disabled it, and apparently that was causing the issue everytime, because Ctrl+Shift+Right/Left worked with this all shortcuts worked fine, after disabling it. In Neon or other explise IDE versions, 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 and all shortcuts start working again. Thanks for your upvotes, this solution might help you!

The easiest solution for me was to Restore Defaults in Preferences - General - Keys.

If you assigned some custom bindings it is possible that something went awry.
