Jenkins closes/saves the project configuration if the user presses RETURN in a text field. If the text field has a Jenkins provided auto-completion (or an auto-completion of a browsers like Firefox) then Jenkins also saves the configuration upon selecting a value in the auto-completion list. This is irritating since the user does not expect that a dialog will be closed due to a selection in a list. Either provide a new shortcut to close/save a dialog (as it is done in Jira using ALT-S) or provide a special handling for ENTER if there is a auto-completion in progress.

Old Issue description:

Under the build triggers block in the job configuration if you check off "Build after other projects are built" and start typing a project name, the auto complete box that offers possible suggestions for jobs you want to set as triggers does not respond to the enter key.

For example I type test, it tells me available jobs are test-1 and test-2, I use the arrow key to scroll down to test-1 and press enter it will save and exit the configuration rather than select test-1 because the enter key is still tied to the save button.

*Also I believe that Projects names is a grammatical error, and should instead be Project names.
