To get help, users have to either leave their context (visit the dictionary) or open a tooltip that disappears once they clicked elsewhere. Users can't compare two definitions side-by-side.
Information Processing Style: Users are only allowed to see a tiny piece of documentation (a transient tooltip) or a huge amount (the dictionary). Comprehensive information processors want the in-between option: All and only the information they need to complete their task.
Tooltips stay open and can be moved anywhere on the screen, such as next to other open tooltips.
Information Processing Style: Users who favor a comprehensive information processing style can expand and pin tooltips (like the ‘for’ tooltip shown in the screenshot) so they can learn about and compare programming commands in a convenient way and at any time.
