This is a simple, focused plugin that changes how you interact with the Eclipse Content Assist (autocomplete) window. It allows you to select the highlighted suggestion by pressing the Tab key, serving as a direct replacement or alternative to the Enter key.
After installing the plugin and restarting Eclipse, pressing Tab when the Content Assist (autocomplete) window appears should immediately select the highlighted suggestion.
If Tab key doesn't work after installation
In most environments, the plugin works immediately after installation. If pressing Tab has no effect, try the following configuration.
- Open your
eclipse.inifile. - Find the
-vmargsline. - Add the following lines below
-vmargs:
--add-opens=org.eclipse.jface.text/org.eclipse.jface.text.source=ALL-UNNAMED
--add-opens=org.eclipse.jface.text/org.eclipse.jface.text.contentassist=ALL-UNNAMED
- Restart Eclipse.
Verified on Windows 11 with Spring Tools 5 (STS 5.0.1) and Eclipse 2018-09 (4.9).
