The new ACE-based SQL query editor is great. Being able to submit the form without using a mouse would be even better.
to ./exec/java-exec/src/main/resources/rest/query/query.ftl adds such support.
I can file a PR with the code if desired.
Functionality (for the documentation):
This JIRA's commit introduces the following to Drill:
When composing queries in the web query editor it is now possible to submit the query text by using the Meta+Enter key combination. This will trigger the same action as pressing the Submit button. On Mac keyboards Meta+Enter is Cmd+Enter. On Windows or Linux is Ctrl+Enter though Linux users may have keymapped the Meta key to another physical keyboard key.
