[ENHANCEMENT] Hovering over a keyword should display its library of origin

[DaniMarts]

Is your enhancement request related to a problem? Please describe.
Currently, to determine which library a keyword comes from, I have to CTRL+click on the keyword. This is inconvenient and interrupts workflow, especially when working with unfamiliar codebases or keywords that are used by multiple libraries.

Describe the solution you'd like
When I hover over a keyword in the code editor or viewer, I would like a tooltip or popup to appear that shows which library defines that keyword. This feature would make it much faster and easier to understand code without needing to navigate away from my current context.

Describe alternatives you've considered

• Continuing to use CTRL+click to jump to the definition, but this is disruptive when repeatedly checking keywords.
• Searching library documentation manually, but this is slow and error-prone.

Additional context
This feature would improve productivity and code comprehension, particularly for new contributors or in large projects with many dependencies.

simple press and hold + and the library or namespace is shown in the editor. Is this enough?
